CoCoRaHS WxTalk Webinars


The CoCoRaHS WxTalk Webinar Bi-Monthly 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:



Webinar #73 - Thursday, November 5, 2020, 1PM EST

The History of Commercial Weather Sector Innovation and Challenges of the Future
Joel Myers
Founder, President, CEO & Chairman

State College, PA


Since he started forecasting the weather in the 1950s, AccuWeather Founder and CEO Joel Myers has witnessed profound progress in the ability of the American Weather Enterprise to provide more specific, more accurate and more useful weather forecasts, warnings, and data, and communicating these with increasing value, thereby saving countless lives, enhancing the national and global economy, and improving the quality of life for billions of people.

These incredible advancements are due to the dedication and numerous innovations in all three sectors – academia, government, and America's Weather and Climate Industry – enhanced by the partnership that has developed between the sectors, and the important role of the American Meteorological Society in facilitating this understanding.

In this presentation, Joel will review key innovations and contributions to this success from the three sectors and especially America’s Weather and Climate Industry. He will examine some past events where weather changed history and address the challenges of the future as we face dramatic changes and transformations in technology and society.
