Super-Fast Jet Makes Jets To Europe Super-Fast

Departures were being delayed from the U.S. to the UK to keep aircraft from arriving to early in Europe. You have to feel for the folks flying from Heathrow to Seattle though; add two hours to an already LONG flight! I experienced this once on a flight from Atlanta to London, and arrived an hour early. We sat on the plane though waiting for a gate to open up!

Seems It Finally Rains In Southern California (and it snows too!)

Heavy rain and snow is moving into California tonight, as an intense surface/upper level low pressure system taps warm tropical air to the south and shoves it into California. California gets most of its rain in winter and you might be surprised to know that most if it comes from just 5-6 storms. The water vapor imagery from the GOES shows the storm well. Keep in mind that you are …

The Governor of New York Owes an Apology to a Bunch of Meteorologists

The Governor of New York, Andrew Cuomo, really stepped in it on Saturday. He’s now getting a firestorm of criticism, and he deserves every bit of it, but I want you to understand why before I go into what he said. There is an old rule among weather forecasters, and it goes like this- “Never forecast a record, you will probably be wrong!”. Now I, and many others, have broken …

Indian Summer For The End of November?

There are growing sign,s that after one more blast of even colder air next week, we will see some much warmer air over the Central and Eastern U.S. as we head into Thanksgiving. Indian summer may be on the way! The forecast below is based on an average of many long-range model runs of the Climate Forecast System. Research shows that an average of model runs provides a more accurate …

Forecasters and Science Writers Knock Weather.Com For Hype

A low-end nor’easter is bringing wind and rain to much of the Northeast U.S. this evening, and Gale Warnings have been posted in the Atlantic as well. As nor’easters go, this is not really a big one, and we will see far worse over the coming months, with some of them bringing snow instead of rain.This is what I told my viewers here in Maryland/ Delaware, and so did many …

How rain falls – not just how much – may alter landslide risk

New research finds that it’s not just the amount of rain that falls on a hillside, but the pattern of rainfall that matters when trying to determine how likely a slope is to give way. This new information could improve forecasts of landslides, which are typically hard to predict, said the scientists conducting the research.
Different rainfall patterns—a short, heavy deluge, a light, steady downpour, or sporadic showers—will trigger different numbers of landslides with varying amounts of debris, according to the new study published today in Water Resources Research, a journal of the American Geophysical Union.

Detecting avalanches from sounds we can’t hear

Researchers have developed a new avalanche monitoring method that uses sound below the range of human hearing to detect and track these deadly and destructive snow slides. The technique can detect an avalanche from the moment it starts, picking up the unheard thump of a rupture in the snowpack that can precede the snow cascade. It can then track the avalanche’s path second by second down the mountain.

In a new study published last month in Geophysical Research Letters, a journal of the American Geophysical Union, scientists report using an array of infrasound detectors on a mountainside to pick up low-frequency sound waves emitted from one of a series of January, 2012, avalanches in Idaho’s Canyon Creek corridor.

Scientists turn Hurricane Sandy destruction into future readiness

This December, USGS will release a beta version of interactive computer models created from data collected by that laser-equipped plane—known as the second generation Experimental Advanced Airborne Research Lidar (EAARL-B)—and other equipment that mapped and monitored the New Jersey coast. The online portal will allow anyone to look at storm intensities and directions, evaluate wave attack scenarios and coastal vulnerabilities, and anticipate the impacts to landscapes ahead of time, said Neil Ganju, a USGS research oceanographer, at a 19 September congressional briefing on the Department of the Interior’s response to Hurricane Sandy.

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 …

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 …

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 …
