An Outbreak Prompts Big Changes

  

On April 3-4, 1974, 148 tornadoes tore through 13 states and Ontario, Canada, claiming over 300 lives in one of the nation's worst tornado outbreaks.

After this super outbreak 40 years ago, several important advances in both science and public awareness of severe thunderstorms and tornadoes were spurred. Some took two decades to fully implement; others were phased in more quickly.

Let's list the things we may take for granted today that were not in place during the 1974 Superoutbreak.

First African Tropical Wave of the Year to Get Designated an 'Invest': 96L

By Dr. Jeff Masters
July 27, 2016

One of the strongest tropical waves of the 2016 African monsoon season moved off the coast of Africa on Wednesday morning, and has the potential to develop into a tropical depression in the coming days as it tracks westwards at 15 - 20 mph into the middle Atlantic. NHC designated this disturbance Invest 96L on Wednesday morning--the first "Invest" of the year for an African tropical wave.

Hottest Reliably Measured Air Temperatures on Earth

As Jeff Masters mentioned in his recent blog, a temperature of 54.0°C (129.2°F) was observed at Mitribah, Kuwait on July 21st. According to the Kuwait Meteorological Department this was the hottest temperature ever measured in the country (a reading of 54.4°C/129.9°F observed at the same site on July 16, 2010 has been disallowed as a result of a faulty sensor). The 54.0°C reading also is a new record for Asia and ties a similar reading at Death Valley (on June 30, 2013) as the hottest reliably measured temperature on Earth. The key word here is ‘reliably’. Many hotter temperatures have been reported from around the world in years past. However, all of these have credibility issues. In that vein I am going to revisit a blog I first posted on WU in October 2010 listing all the various claims to temperature readings at or above 54°C (129.2°F). In the years since I made that post I’ve learned more about some of these claims and have thus updated my entries and ‘validity’ scores as a result.

The confluence of meteorological ingredients the first weekend in October 2015 resulted in an extraordinary weather event with severe impacts. Was one of them a 1000-year flood?

Why the Arrest of a Science-Loving 14-year-old Matters

By Shaun Tanner

By now, many of you have heard or read about the arrest of Ahmed Mohamed, a 14-year-old high school student from Irving, Texas. Ahmed was arrested because school officials called the police after he showed one of his teachers his homemade clock. Mistaken for a bomb, Ahmed was taken into custody, interrogated, shamed, suspended (still on suspension today, Wednesday), and reprimanded. All of this after it has been found that the "device" he brought to school was indeed, a homemade clock.
