Why the Monsoon Means More Haboobs
9 Jul 2018 10:28 PM
By now you've probably heard us meteorologists talking about the summer monsoon.
A monsoon doesn't have anything to do with rain. In fact, it's more about the seasonal shift in wind direction that in turn brings more moisture to a given region.
Here's a little more on that:
What is a Haboob?
For starters, let's get this Haboob thing all sorted out.
If you don't want to click the article and do a little reading. Let me sum this up for you.
A haboob is a dust storm. You know, that wall of dust coming at the camera in all of those cool photos.
The article headline could have read, "Sand Storms" or "Dust Storms" but where's the fun in that!?
How the Monsoon Causes More Haboobs
Talk about burying the lead!
You see, a haboob needs a thunderstorm in order to form.
All thunderstorms produce strong winds that flow downward and outward from the parent storm. Anywhere else in the country, those winds are relatively uneventful. However, the arid climate changes things for the Southwestern U.S.
All of the sand and dust down on the surface is lifted by that strong outflow. The winds carry the debris into the air– creating that wall of sand or dust!
During the summertime monsoon thunderstorms are much more prominent across the desert Southwest. Therefore, haboobs occur more often!
Now check out this awesome time lapse from Phoenix that show this exact thing!
This storm knocked out power for almost 75,000 residents in the Phoenix metro.
All Fun Aside
Haboobs can actually be dangerous.
