Every week, the blog introduces you to a technical term from the American Meteorology Society’s “Glossary of Meteorology”. Welcome to #WxGeekSpeak!
It’s Mother Nature’s version of a block party. Chances are, it will blow you away. Click the video above to learn about the Rex Block & its impacts on southern Arizona.
Full definition of Rex Block: In meteorology, blocking happens when centers of high pressure and low pressure set up over a region in such a way that they prevent other weather systems from moving through. While the block is in place other systems are forced to go around it. Blocks can remain in place for several days, resulting in monotonous weather for locations under the block.
