CoCoRaHS WxTalk Webinars


The CoCoRaHS WxTalk Webinar Series

In December 2011 CoCoRaHS kicked off a new and exciting monthly Webinar series called CoCoRaHS WxTalk (wx is shorthand for weather). CoCoRaHS WxTalk consists of a series of monthly one-hour interactive Webinars featuring engaging experts in the fields of atmospheric science, climatology and other pertinent disciplines. These easy to follow presentations are live and approximately sixty minutes long. The audience is given the chance to submit questions which the experts answer live on the air.

Topics have included: Snow, Satellites, Hurricanes, Lightning, Clouds, Tornadoes, Flash Floods, Fire Weather, Weather History, Radar and How to become a Meteorologist, just to name a few.  

There are many exciting Webinars on the agenda in the months ahead, so please tell your friends to join us.  All WxTalk Webinars are free and most are recorded for later viewing.

*Although headphones are a good way of listening to the Webinars, only a set of speakers is required to hear the Webinar.  The audience will be muted so there is no need for a microphone. All incoming correspondence during the Webinar should be in typed form.

Upcoming WxTalk Webinars:

Thursday, May 5, 2016 - 1PM EDT

The Weather and Climate of the Plains: The Land of Extremes
Natalie Umphlett
Interim Director/Regional Climatologist
High Plains Regional Climate Center
Lincoln, NE


Nestled in the interior of North America lies the Great Plains, which stretches over 2,000 miles from Texas in the south through portions of Canada in the north. This region is known for its expansive skies, filled with billowing clouds and fiery sunsets. The geography of the region, with the Rocky Mountains to the west and the Gulf of Mexico to the south, contributes to a defining feature of the plains – its strong east to west gradient in precipitation. Early travelers on the plains would have experienced this through the transition from tall to short grass prairies and modern day travelers can see this as the trees in the east and scrubland in the west whiz by. The area is also prone to a wide variety of extreme weather and climate events, including heat waves, cold waves, flooding, drought, and blizzards, in addition to high winds, hail, and tornadoes from thunderstorms. Recently, the region suffered back to back extremes, with historic flooding in 2011 followed by historic drought in 2012.


Thursday, June 23, 2016 - 1PM EDT

Weather, climate and extremes in the western U.S.
Nina Oakley
Western Regional Climate Center
Reno, NV


The Western Regional Climate Center services 11 western states including Alaska, Hawaii, and the US API. Our region boasts a diversity of climates including both hot and cold deserts, temperate and tropical rainforests, and alpine tundra. The main drivers of climate in much of the West are its latitudinal range, proximity to the vast Pacific Ocean, cool coastal currents, and abundance of mountainous terrain.

The West is also home to a variety of extreme weather phenomena that are often distinct from the tornados, hurricanes, and blizzards observed in the central and eastern parts of the country. Narrow corridors of high water vapor transport called atmospheric rivers produce intense rainfall and flooding when they encounter the rugged terrain of the West Coast. Extreme terrain-enhanced winds are also a common hazard during the passage of frontal systems. Wintertime inversions that induce hazardous air quality are commonplace in populated basins of the Intermountain West. Dangerous flash flooding occurs frequently in the Southwest and Great Basin during the summer when the North American Monsoon kicks in, and dying tropical storms have been known to brush the Southwest inducing heavy rainfall.

This presentation will explain the drivers of weather and climate of WRCC’s region within the conterminous US as well as explore some of its exciting extreme events! 

Thursday,  July 14, 2016 - 1PM EDT 

The Climate of the Southeast U.S.: Geographic Patterns and Trends in Extreme Weather Events
Chip Konrad
Southeastern Regional Climate Center
Chapel Hill, NC


Chip Konrad will introduce the climate of the Southeast U.S., emphasizing how it varies across the region and how it compares with the rest of the country.   He will discuss the different types of extreme weather events that impact the region, including hurricanes, floods, heat waves, droughts and tornadoes.  Specifically, he will reveal trends in the frequency and occurrence of these extremes over the last century.  He will conclude with a short discussion of how the frequencies of these extremes may change over the next century.  

Thursday, August  4, 2016 - 1PM EDT
