Maria Back Over Water After Devastating Hit to Puerto Rico

Dr. Jeff Masters  ·  September 20, 2017, 5:53 PM EDT

SNIPPET 1:

After making landfall in southeast Puerto Rico near 6:15 am Wednesday as a top-end Category 4 storm with 155 mph winds, Hurricane Maria finished a devastating pummeling of the island near 1:30 pm, when its eye emerged over the ocean off the northwest coast. An Air Force hurricane hunter aircraft found that Maria’s 70-mile traverse of Puerto Rico had knocked the top winds of the storm down to 110 mph by 5 pm Wednesday, making it a high-end Category 2 hurricane. Satellite images show the hurricane is still well-organized, though, and the Hurricane Hunters found that Maria’s pressure was falling again late Wednesday afternoon: 957 mb at 5 pm, compared to a 961 mb reading at 2 pm. Maria will continue to bring dangerous torrential rains and powerful winds to Puerto Rico and the eastern Dominican Republic into Thursday.

Maria brought extreme rainfall amounts to large portions of Puerto Rico that caused record or near-record flash flooding. Numerous stations in Puerto Rico recorded rainfall amounts in excess of ten inches. Rainfall amounts in excess of 47 inches in 24 hours were recorded at three stations on the southwest side of El Yunque, the high mountainous area in the northeast corner of Puerto Rico; these are so extreme as to be unbelievable, and the gauges may have been impacted by flash flooding, or by a callibration problem at extreme precipitaion rates:

96.65” at Quebrada Arenas, including 67.75” in one hour ending at 6 am.  :o
72.07” at Barrio Montones, including 34.04” in one hour ending at 8:45 am.  :o
47.25” at Rio Valenciano, including 19.66” in one hour ending at 7:11 am.
 

These rainfall amounts would break virtually every world record for precipitation, and are highly likely to be in error. Water levels at the Rio Gurabo at Gurabo, where the nearby Gurabo Abajo rain gauge recorded 23.64” of rain in less than 24 hours, jumped by 27 feet in less than 12 hours (see Figure 2), so that rainfall amount is believable.

An island-wide power outage in Puerto Rico

Not since the great Category 5 1928 San Felipe Segundo hurricane has Puerto Rico experienced a hurricane catastrophe as extreme as that wrought by Hurricane Maria. The storm’s powerful winds caused catastrophic damage to the island’s power grid, knocking out power to 100% of Puerto Rico’s 3.4 million residents. In the Virgin Islands, there was also heavy damage on St. Croix, and serious flooding has been reported on St. Thomas. Maria is almost assured to be the most expensive hurricane in Puerto Rico history, and may challenge Hurricane Hugo (1989) and Irma (2 weeks ago) as the most expensive hurricane on record for the U.S. Virgin Islands.

SNIPPET 2:


Figure 5. The four rapid-intensifier hurricanes of 2017, compared with Hurricane Wilma of 2015. Shown are the last periods in which the hurricanes were at various levels (tropical depression, tropical storm, or Category 1 hurricane) along with the intervals from that point to the first point at which they achieved their top rating (either Cat 4 or 5).

This year is chock-full of rapidly intensifying hurricanes

If it seems like this year’s Category 4 and 5 storms made it to that level in a big hurry, you’re not imagining things. In the Washington Post, Chris Mooney spotlights a few of the leaps in strength that this year’s four major Atlantic hurricanes have taken, including:

Harvey:  Cat 1 to Cat 4 in 24 hours
Irma:  Cat 3 to Cat 5 in 24 hours
Jose:  Cat 1 to Cat 4 in 24 hours

Maria:  Cat 1 to Cat 4 in 12 hours, and Cat 1 to Cat 5 in 15 hours

Most of the rapid intensification records for major Atlantic hurricanes were set by 2005’s phenomenal Hurricane Wilma. However, Maria has tied Wilma for the fastest vault from tropical depression to Cat 5 hurricane (54 hours), as shown in Figure 5 above.

Agelbert NOTE: The radome that protects the radar I used many years as an air traffic controller, which is supposed to be able to withstand 200 mph plus winds, was heavily damaged, putting the radar out of service just as Hurricane Maria was making landfall.

The radome is located on a 4,300 ft. mountaiin peak about 18 miles north of the eye of Hurricane Maria in the graphic below:

That has NEVER happened since that radar dome was built several decades ago. This hurricane's winds near the peak where the radome is must have been OFF THE CHARTS! Welcome to Catastrophic Climate Change.

Profit Over People and Planet Pollution Sources next to Houston Ship Channel 

Analyzing the 5.5 Million Pounds of Air Pollutants Released in Texas After Harvey
Wednesday, September 20, 2017

By Janine Jackson, FAIR | Interview

SNIPPET:

Janine Jackson: The story of devastating weather events like hurricanes is many stories, really. There's no need to compete; they're all critical. But there is something about the oil industry spurring climate disruption, lobbying against preventative or preparatory measures, and then adding to its harmful impact with their methods of operation. As Texas continues to reel under the effects of Harvey, it's been noted that besides massive flooding, some communities were also faced with dangerous chemicals released into the air by refineries and petrochemical plants.

How did that happen, and what can prevent it from happening again? Our next guest has been investigating that. Shaye Wolf is climate science director for the Center for Biological Diversity. She joins us now by phone from Oakland. Welcome to CounterSpin, Shaye Wolf.

Shaye Wolf: Thank you for having me.

After the Hurricane, Solar Kept Florida Homes and a City's Traffic Lights Running

By using energy storage with solar panels, some homeowners were able to go off-grid, showing how distributed power could speed future storm recovery.   

BY LYNDSEY GILPIN, INSIDECLIMATE NEWS

SEP 15, 2017

SNIPPET:

Unlike large swaths of Florida that were facing days if not weeks without electricity, Pereira knew he would have power when the sun rose. He had installed rooftop solar panels two weeks before the storm, along with an inverter that allows him to use power from the solar panels without being connected to the grid. The next morning, he plugged an extension cord into the inverter, flipped it on, and let his 7-kilowatt rooftop solar array do the rest. He was able to use his appliances and his Wi-Fi, so he could continue his work as a home-based IT consultant while the neighborhood waited for grid power to came back on.

"We didn't have sun at all the day after the hurricane, but even with clouds, it was enough," he said. 

Hurricane Irma cut the power to about 6.7 million customers across Florida, as well as hundreds of thousands in Georgia, South Carolina and North Carolina. Only about two-thirds of those in Florida had power back by Thursday, and Florida Power & Light said the outages could last weeks in some areas.

Are the models “running too hot”?   


September 20, 2017 GCMs, observations Ed Hawkins

Recent media headlines have again discussed the issue of whether climate models are overly sensitive to greenhouse gases. These headlines have misinterpreted a study by Millar et al. which was discussing carbon budgets to limit global temperature rise to 1.5°C above pre-industrial levels.

A recent study by Medhaug et al. analysed the issue of how the models have performed against recent observations at length and largely reconciled the issue. An overly simplistic comparison of simulated global temperatures and observations might suggest that the models were warming too much, but this would be wrong for a number of reasons.

In the Medhaug et al. paper they show the range of models (blue shading in figure with median in light blue), compared with the HadCRUT4 observations and their estimated uncertainty (orange shading with light orange line). There are a number of well understood reasons why the light orange line might not follow the light blue line, namely: radiative forcings, variability, observational biases and choice of reference period.

Figure 5 from Medhaug et al. showing CMIP5 simulations and observations (HadCRUT4) of global temperature.

Radiative forcings: The simulations were produced using observed information on sources of radiative forcing up to 2005, and made various assumptions for subsequent forcings. For example, the simulations assumed no volcanic eruptions after 2005, whereas the real world did have some eruptions. In addition, the sun dimmed slightly and this was not included. Retrospectively we can estimate the effects of these assumptions on the simulations, and this moves the light blue line to the mid-blue line. In other words, if the models had known about future forcings they would have been closer to the observations.

Variability: It is also understood that natural fluctuations in the climate (e.g. ENSO, PDO) can temporarily offset or enhance the warming during certain periods. These effects can also be accounted for, producing the dark blue line. In other words, if the models had produced the same phase of variability as the real world then, again, they would have been closer to the observations.

Observational biases: We also understand that our observations are not perfect. The HadCRUT4 dataset has relatively few observations over the Arctic and also uses sea-surface temperatures over the ocean, whereas the model analysis uses simulated air temperatures everywhere. Accounting for these issues moves the observations warmer, to the dark orange line. In other words, in an ‘apples-with-apples’ comparison, the observations and models are closer together.

When accounting for these three factors together, the dark blue and dark orange lines now show a very similar warming trend – the models and observations have been reconciled and there is no clear evidence from the recent period that the models are therefore ‘running too hot’. About 1/3 of the apparent discrepancies are due to each of these three factors.

Choice of baseline: One further subtlety is the choice of ‘baseline’. Medhaug et al used a 1961-90 reference period, whereas the IPCC AR5 chose 1986-2005. This difference can also slightly move the relative position of the observations within the model spread higher or lower. There is no perfect choice.

Agelbert NOTE: IOW, the "models may be running too hot" BALONEY is more disingenuous spurious propaganda cooked up by the fossil fuel industry crooks and liars to undermine the credibility of climate scientists.

If anything, the models are too conservative. This type of Orwellian pitch has been par for the course for the fossil fuel industry for several decades.

If you doubt that, just consider the fact that they were the ones that came up with that CRAP about a "new ice age".

So, expect more wailing and moaning about "alarmist" climate scientists from the bought and paid for propagandists from the fossil fuel industry  , for the "welfare of humanity"(see Orwell), of course.

Over $2 Billion In US Fire Suppression Costs From This Year’s Wildfire Season

September 19th, 2017 by James Ayre

SNIPPET:

That figure represents a substantial increase from the previous record year of 2015, which saw the agency spend $1.7 billion on fire suppression efforts.

To be clear here, these figures relate solely to US Forest Service costs and don’t include figures from federal, state, or local firefighting agencies.

Altogether, 2017 has been an unprecedented year in the US (and in many other parts of the world as well) with regard to forest fires. At this point, it should be clear that the predictions that wildfires will become increasingly common and severe over the course of the century as a result of anthropogenic climate change have something substantial to them.

Maria Headed for Catastrophic Hit on Puerto Rico, St. Croix
Bob Henson  ·  September 19, 2017, 11:41 AM EDT

SNIPPET:

After a direct hit on the small Lesser Antilles island of Dominica on Monday night, followed by a brief weakening, Hurricane Maria reintensified to Category 5 strength with winds of 160 mph on Tuesday morning. Maria will likely be a catastrophic Category 5 or high-end Category 4 storm when it hits the U.S. Virgin Islands and Puerto Rico on Wednesday morning. Preliminary reports out of Dominica indicate that Maria likely did catastrophic damage there. The northern eyewall of Maria also grazed the southwest corner of Guadaloupe Island on Monday night, and heavy damage was reported there. The core of the hurricane missed Montserrat, Saba, and St. Kitts and Nevis, but these islands have been experiencing sustained tropical storm-force winds and heavy rain squalls.

Maria’s encounter with Dominica bruised the storm slightly, with the top winds falling to 155 mph and the central pressure rising from 924 mb to 934 mb between 11 pm Monday and 5 am Tuesday. This took the storm briefly down to a Category 4 rating. However, an Air Force hurricane hunter aircraft on Tuesday morning found a falling pressure and rising winds. Maria’s central pressure was down to 927 mb, and the winds were back up to 160 mph as of 11 am EDT Tuesday. Maria passed just east of Buoy 42060 late Tuesday morning; the buoy reported a pressure of 956 mb and sustained winds of 74 mph, gusting to 94 mph, at 11:10 am EDT Tuesday.

Unfortunately for the islands in its path, Maria’s appearance on satellite imagery is truly spectacular, and the outer spiral bands of the hurricane are already lashing the Virgin Islands and Puerto Rico, as seen on long- range radar and CatherineHope’s Webcam on St. Croix.


Figure 1. GOES-16 visible image of Maria at 10:15 am Tuesday, September 19, 2017. At the time, Maria was a Category 5 storm with 160 mph winds, a central pressure of 927 mb, and a small "pinhole" eye with a diameter of 10 nautical miles. Image credit: NOAA/RAMMB. GOES-16 data is considered preliminary and non-operational.

The dreaded "pinhole" eye  

Maria developed a tiny “pinhole” eye during its rapid intensification burst on Monday, with a diameter of 8 nautical miles (nm). The hurricane has maintained a small eye so far on Tuesday, with the diameter fluctuating between 7 nm and 10 nm (10 nm = 11.5 miles). Hurricanes that develop pinhole eyes often intensify into some of the strongest storms we observe, since they concentrate their wind energy around a narrow ring surrounding the tiny eye. These small eyes tend to be unstable, resulting in an eyewall replacement cycle (ERC) shortly after the pinhole eye is observed. Some other examples of tropical cyclones with pinhole eyes with a diameter less than 10 nm (thanks go to Michael Cavaliere, Howard Diamond, and Boris Konon):

Hurricane Wilma - 2005 (175 MPH / 882 MB) - Western Caribbean - 1.5 nm
Hurricane Iris – 2001 (140 MPH / 950 MB) - Western Caribbean – 3 nm
Hurricane Beta - 2005 (115 MPH / 962 MB) - Nicaragua - 5 nm
Hurricane Dennis - 2005 (120 MPH / 930 MB) - Florida - 4 nm
Hurricane Charley - 2004 (150 MPH / 941 MB) - Florida - 2.5 nm
Hurricane Opal - 1995 (150 MPH / 919 MB) - Florida - 5 nm
Hurricane Andrew - 1992 (165 MPH / 921 MB) - Florida - 6 nm
Typhoon Forrest - 1983 (165 MPH / 883 MB) - Philippines - 4 nm
Cyclone Tracy - 1974 (125 MPH / 950 MB) - Australia - 7 nm

Why Are Ice Cubes Often Cloudy?
 

Tap water typically contains benign impurities such as lime, calcium, fluoride, nitrates, magnesium, and other organic elements. When water freezes, it hardens from the outside in, and those impurities are pushed into the center of the cube, causing the ice to have a cloudy appearance. However, boiling the water first will remove most of the impurities and provide clearer ice.

Ice, ice, baby:

Using bottled water that has been purified using a reverse osmosis process, or another type of distillation, will also improve ice cube clarity.

Cloudy ice is also related to how quickly the water is chilled. Most home freezers cool very rapidly, and tiny air bubbles (actually, dissolved air) get trapped before they can dissipate.

High-end restaurants use systems that freeze pure water slowly, in layers, so that air bubbles have plenty of time to escape.

Six Storms Bracket North America: 3 hurricanes, a tropical storm, depression & a disturbance

Paul Beckwith

Published on Sep 17, 2017

At this moment we have three hurricanes (Jose, Maria, & Otis), a tropical storm (Norma), a tropical depression (Lee) and a tropical disturbance (yet unnamed) surrounding North America.

I discuss the latest projections, and teach you the tools to track these storms yourself. Hurricane Jose is expected to curve northward off the US coast, while Hurricane Maria is likely to rapidly strengthen and bring pain to many Caribbean Islands hurt severely by Hurricane Irma.
