Saharan Dust Storm Below Towering Thunderstorms

Here are the particulars of the image, and what you are seeing from NASA Earth Observatory: More dust blows out of the Sahara Desert and into the atmosphere than from any other desert in the world, and more than half of the dust deposited in the ocean lifts off from these arid North African lands. Saharan dust influences the fertility of Atlantic waters and soils in the Americas. It blocks or reflects …

Crazy Summer Weather pattern Is About To Flip

The summer of 2014 has been unusually mild in the Midwest and portions of the East, and brutally hot and dry in the West. The heat and drought in the NW corner of North America has led to raging forest fires that have spread dense smoke over the northeast and across the Atlantic to France, and the drought in California has reached the worst possible level: exceptional drought. Mother Nature is …

This Is Why Canada and The West Are Burning

NASA posted this map of the temperature anomalies over North America for July, and you can easily see why we there is so much wildfire activity in the U.S. West and Canada North. This is why dense smoke is travelling thousands of miles to the Eastern Seaboard. The heat out west has now pushed much of California into Exceptional Drought” status.

Wildfire Smoke Makes Cool East Coast Temps Even Cooler

In spite of an unusually dry and cool air mass over the eastern seaboard of the U.S. this afternoon, the sky is a milky white due to smoke from the wildfires in Western and far northern Canada. An even denser layer of smoke covers the western portions of Hudson Bay as well. Here is the view of the sky over Maryland at 630 PM, and the usual deep blue sky …

Dropped cell phone calls become rain gauges in West Africa

A shaky cell phone connection during a rainstorm can be an annoying nuisance. But now scientists are showing that these weakened signals can be used to monitor rainfall in West Africa, a technique that could help cities in the region better prepare for floods and combat weather-related diseases.

The Great Facebook Blizzard of 2014

At the AMS Broadcast Meteorology conference last month in Lake Tahoe, I presented a talk about widespread rumors on Facebook last January that a paralyzing snowstorm was coming. This is just one example of the love/hate relationship that meteorologists have with Facebook, and I was quoted in an article on TV News Check about this as well a couple of weeks ago. As I told the reporter for TV News …

Mid-Summer Taste of Autumn Next Week? Probably!

What is going on? Is it the revenge of the polar vortex? Actually, it’s probably connected to Japanese Typhoon Neogori that at one time was packing 260 kph winds. It is moving into southern Japan now, but the global weather models all indicate that it will push a lot of warm and humid air into the high latitudes north of Japan. This will push the jet-stream northward, and the downstream …

Indefensible Ignorance

I spotted this online today, and believe me it is being shared far and wide in science circles. A statement like this from a 5th grader would be alarming, but from someone (State Senator Brandon Smith) who makes laws is downright frightening. What is more frightening is that the science literacy of his constituency is so low, he’ll likely be easily re elected. In case there are any doubts I …

The Weather 238 years ago today in Philadelphia- Courtesy of T. Jefferson

It was cloudy in Philadelphia. Weatherwise Magazine has an excellent article with more about Jefferson and his weather records. Truly he was America’s first Meteorologist.

Meteorology In The High Mountains Of California

  I am at the American Meteorological Society’s 42nd Conference on Broadcast Meteorology at Squaw Valley,Ca. We are just outside of Lake Tahoe, and I drove up from Las Vegas, through Death Valley and by Mammoth Lakes. The temperature ranged from 96 in Death Valley to 46 at Mammoth, and when i awoke here in Squaw Valley this morning it was 28 degrees! I thought I’d share some pics of …

Some Amazing Pics Of Earth

  NESDIS is now producing some incredible Earth imagery using different satellites with some of the most sophisticated radiation sensors in orbit. I thought I would share  a couple with you. Click for the BIG image. One is a view of the USA taken Saturday afternoon June 7. The other is the sea temperatures around North america and the other shows the temp. anomalies. This allows you to see where …

Here’s How Scientists Are Improving Warnings of Dangerous Weather

  Imagine a hot July weekend, and the beaches and or area lakes are packed with thousands of folks enjoying the sun, sand and water. While there is a chance of thunderstorms in the forecast, the skies are sunny, and the weather is the last thing on the minds of most people. It’s the first thing on the minds of weather forecasters, however, and if strong thunderstorms with deadly lightning …

Can You Think Like A Forecaster??

  Any ideas?? Pretend you’re a forecaster, and you need to make a short term forecast for the area I have delineated. Will you forecast it to stay clear? I’ll post the answer below tomorrow! Fellow meteorologists, you are NOT allowed to guess! (you should immediately know the answer!).   Answer below, but think about it for a few mins. What could have been happening before. What kindof clouds are …

Wichita Kansas Reaches 102 degrees Sunday. Earliest 100+ in 126 years of Records.

The high made it to 102 today in Wichita. From NWS Wichita: 125 km to the south, a massive wildfire is underway this Sunday evening in Guthrie,OK. Pictures from local TV show the extent. The area of EXCEPTIONAL DROUGHT continues to grow. In the Great Plains, all heat and drought are compared to the height of the dust bowl in 1936. A dry spring means a hotter ground, and this …

Predicting Weather & Climate- Gavin Schmidt’s TED Talk is A Must See

I use atmospheric models everyday, and without them the forecast you see on TV or online everyday would be worth little beyond about 48 hours (it would not be very accurate within that time period either). These days, a seven-day forecast will verify much better than a three-day outlook was in the 1970′s, and the improvement continues. Unfortunately, some people see these models as untrustworthy black boxes, and have little understanding …

Death Toll Mounting In Deep South

Below is what the radar image showed. The blue is wind toward the radar and the red is away from the radar. Virtually all of the tornadoes were inside the moderate risk area issued by the Storm Prediction Center. Severe weather forecasting has improved dramatically over the last 30 years.

Major Severe Weather Outbreak Underway In Plains/Southeast

A strong low pressure system is really winding up in the Plains this Sunday evening, and winds are gusting to 48 mph behind  dry line front through Oklahoma and Texas. Ahead of the dry line, a moist and extremely unstable airmass is in place, and storms have already developed. Keep in mind that tornadoes require both unstable air AND strong low-level wind shear, and there is plenty of both in …

Oh, The Things You Can See From On High

I spent a little while looking at today’s images from NASA’s Terra and Aqua satellites with their amazing MODIS imager that sends back true colour images from an altitude of around 700 km. Here are a few things I spotted in just a short period of browsing this evening. Click any image for a much larger view. Here is a view of just some Sahara sand blowing north into Greece …

New Research Shows Asian Soot Cloud Affecting Pacific Storms

A group of researchers from Texas A & M University have a paper in the Proceedings of the National Academy of Sciences (PNAS) this week that is getting a lot of attention. Cloud droplets and rain drops need something to form on, and without dust and other aerosols in the atmosphere we would see a lot less of both. Sometimes though, the addition of particulates can cause tiny cloud droplets …
