March 2nd, 2012

During the afternoon and evening of March 2nd, 2012 nine tornadoes touched down in the WKRC-TV viewing area.  Tornadoes are rated using the EF scale or the Enhanced Fujita Scale.

  Of the nine tornadoes that touched down, there were two EF's, two EF1's, two EF2's, two EF3's, and 1 EF4 tornadoes.  EF3's, EF4's, and EF5's only make up 5% of all tornadoes that occur.  The three strongest tornadoes hit Holton IN, Piner/Crittenden KY, and Peach Grove KY/Moscow OH. 

Above is what the National Weather Service radar from Wilmington Ohio during the afternoon and evening of March 2nd, 2012.  Tornadic supercell developed across southern Indiana and then moved at 60mph into Northern Kentucky.  These supercells were alive for over 200 miles.  The thunderstorm which created the Holton Indiana tornado spawned a tornado and dissipated shortly thereafter.  Let's look at these three tornadoes, one by one.

My Sincere thanks to the National Weather Service in Wilmington Ohio for providing the track maps and radar images.  Below are the Severe Thunderstorm Warnings and Tornado Warnings issued on March 2nd, 2012.

Kelvin Helmholtz Clouds in Birmingham, Alabama

December 16th, 2011

These "wave-like" clouds were seen in Birmingham, Alabama today.

The clouds are called Kelvin Helmholtz clouds and are named after

Lord Kelvin and Hermann Von Helmholtz.  The formation indicates

extreme turbulence in the atmosphere associated with vertical wind shear,

or winds changing in speed with height.  The higher winds above the surface

scoop the top of the cloud layer into wave-like rolling structures.  As in the

ocean, the wave crests are pushed ahead of the troughs.

Below I have posted a picture form downtown Birmingham and

and a video taken from the same area.

Haboob Hits Phoenix!

Haboobs are rolling dust and sand clouds formed by collapsing thunderstorms.  When thunderstorms collapse winds rush to the surface and spread out along the ground.  The strongest winds spread in the direction that the thunderstorm is moving.  The southwest has been very dry lately so this collapsing thunderstorm had alot of loose dust and sand to work with as it formed a dust and sand cloud some 5000 feet high and up to 100 miles long.  The haboob was moving at some 50mph and created visibilities near zero.
