Satellites Show the Lack of Power In Puerto Rico as a Catastrophe Unfolds.

The images and pleas for help coming from Puerto Rico are heartbreaking and increasingly alarming. Media reports this evening are saying that 80% of the island’s crops have been destroyed. Only those with generators have power and mobile signals are sparse and intermittent. Up to 60% of people have no reliable access to clean water, and frankly, I can see no signs that much is being done about it! I …

Our Past Climate Is A Warning For the Future

There are some excellent books for non-scientists about our climate, but some of the best are written by Brian Fagan- an Archaeologist! His book The Long Summer is superb, and I am currently listening to a series of lectures he made for The Great Courses. Any story of human history is incomplete without looking at the role of climate, and in The Long Summer, Fagan points out that all of written …

WMO verifies highest temperatures for Antarctic Region

A World Meteorological Organization (WMO) committee of experts has announced new records for the highest temperatures recorded in the Antarctic Region as part of continuing efforts to expand a database of extreme weather and climate conditions throughout the world.

Meteorological Winter Ends With Record Warmth and Storms

It has been an amazing if not astonishing February across the U.S. Very little snow and record highs falling by the thousands! So far in February, we have recorded 5857 record highs and only 97 record lows. There were 408 stations that had the warmest temperature on record for any day in February and only one station saw the coldest temp. on record for February! Look at the monthly temperature …

Weather patterns, trans-Pacific pollution cause spring ozone spikes in SW US

Late spring and early summer is when the air quality is generally good across most of the United States. But newly published research details how a common springtime weather pattern and pollution transported from Asia often conspire to create unhealthy ozone levels for the desert southwest. The new study adds to a growing body of work that explores how ozone can occasionally push some areas of the desert southwest above federal air quality standards.

NOAA- 2016 Second Hottest on Record in U.S.

Only 2012 was hotter than 2016 in the U.S., by .5 degrees F. It will not be official for a few more days but 2016 will be the hottest year globally as well for the third consecutive year. NASA will have their data out first and then NOAA.  and the Arctic Sea ice looks to be in a free fall…. via GIPHY

Snowflake variability has significant impact on remote sensing of snowfall rates

Every snowflake is unique—and that could have a big effect on determining how much snow will fall, according to new research.

Science Books Make Great Holiday Gifts – Especially These!

There are few gifts better than books, so here’s a list of great science books for ages 13 and up, along with a brand new entry that is rapidly becoming a best seller. First, is Carl Sagan’s 1997 classic The Demon Haunted World. I frequently quote from it, and every true science geek will tell you they love this book. If it were up to me, it would be required …

Winter is Coming. It May be a Memorable One.

This is a guest post from my weather intern Andrew McCormick (Senior at Salisbury University here in Maryland). We’ve been looking at what the winter may bring for a month or so now, and Andrew has a good track record of past winter forecasts. This is a good summary of the techniques we use to make long range forecasts, and in case you’re wondering, I see nothing to disagree with …

Record Low Temperatures Are Dissapearing

Guy Walton is the former lead forecaster for the Weather Channel, but most of us meteorologists know him these days as the person who keeps track of the “ratio of record highs vs record lows”. As the planet warms, we should expect to see more record highs and fewer record lows, and the data is indeed showing just that. It’s actually impossible to miss, because the ratio itself is in …

New study “reels in” data on Utah’s winter ozone problem

A deep sea fishing rod is probably not the first tool that comes to mind when thinking about how to study air pollution in a remote inland desert, but it’s the heart of a new system that has given scientists a minute-by-minute look at how quickly the sun can convert oil and gas emissions to harmful ground-level ozone.

Extreme-weather winters are becoming more common in U.S., research shows

The simultaneous occurrence of warm winters in the West and cold winters in the East has significantly increased in recent decades. The damaging and costly phenomenon is very likely attributable to human-caused climate change, according to a new study.

Wildfire smoke hacks clouds

Plumes of wildfire smoke envelop and alter clouds, potentially affecting local weather, according to new research based on serendipitous airborne measurements of clouds in smoke from Canadian fires. The new data confirms clouds embedded in smoke are likely to warm up the atmosphere around clouds, causing the clouds to dissipate faster.

Study identifies link between cold temperatures in New York, destructive storms in Spain

In a recently published study, researchers show there’s a common atmospheric circulation pattern linking extreme weather on the two sides of the Atlantic Ocean.

The Heat, the Floods, and the Danger of Underestimating How to Handle it.

The NASA Terra satellite measurements of ground temps. in the early afternoon clearly show the heat, and the extra heat added by the urban concrete (and road systems) was clearly visible. On a day like today, large cities can be much hotter than the rural areas. Also, notice how the temps near the Delaware coast are hotter than inland in Delaware (and here on the Eastern Shore of Maryland). A …

Up to 8 Inches of Rain Fall on the Eastern Shore of Maryland

I live here on the Eastern Shore of Maryland, and we had a severe flood event last night. Nearly 6 inches of rain fell at my house. This comes after my post yesterday about the difficulty in forecasting extreme events like floods. Look below and read what I posted to my local viewers about the event. This area is flat, so we did not have any loss of life, but …

Congressman’s idea to privatize NWS forecasts gets icy reception among broadcast meteorologists.

By Dan Satterfield I’m hearing a lot of talk among my fellow forecasters about legislation (introduced by an Oklahoma congressman) that would privatize many forecast functions of the NWS. You might think that private sector meteorologists would support this, but almost every broadcast metr. I know has panned the idea. The quality of public weather forecasts is due to the cooperation between the public and private sector, and a survey of …

Climate change could cause more concentrated storms

Rising temperatures are causing heavy rain storms to become concentrated over smaller areas, a scenario that could potentially cause extreme flooding in urban locations, according to new research.

Asian irrigation influences East African rain

Irrigation from agriculture can directly influence climate thousands of kilometers away and even leap across continents, new research finds. Up to 40 percent of the rain in some regions of East Africa can be attributed to irrigation used in agriculture in Asia, according to a new study published in Geophysical Research Letters.
