#8:  Haboob:  Desert Southwest

My favorite weather video we receive each summer is from the Desert Southwest.

Some thunderstorms, particularly in the western U.S., produce very little rain.  Precipitation falling into a very dry low-level air mass evaporates, chilling the air and causing it become more negatively buoyant, crashing to the ground and spreading laterally, like spilled milk.  

When this happens in the desert, huge clouds of dust can be kicked up, leading to an advancing brown cloud of dust known, or "haboob."  This term originates from the Arabic word for wind:  habb.  

To be sure, these dust storms are dangerous.  Suddenly-reduced visibility can lead to chain-reaction traffic accidents, sometimes with deadly results.  The choking dust can irritate your respiratory system, not to mention leave grit in your teeth.  

I think this bucket list item for me involves two things:  1) Fly in a helicopter well ahead of the haboob and 2) set up a timelapse on the ground of the haboob's passage.  

From dry and dusty to flooding of a historically flood-prone iconic city, let's check out #7 on the list.

QuikSCAT's Replacement, the RapidScat Ocean Wind Sensor, Installed on Space Station

A QuikSCAT replacement called ISS-RapidScat was successfully launched on September 20, 2014 on a SpaceX Dragon cargo spacecraft, which docked last week with the International Space Station (ISS.) This morning, astronauts on the ISS used the station's robotic arm to pluck RapidScat out of the Dragon and install it on the Space Station. RapidScat will measure near-surface winds over the ocean.

What the 5th IPCC Assessment Doesn't Include

By Angela Fritz
September 27, 2013

Melting permafrost has the potential to release an additional 1.5 trillion tons of carbon into the atmosphere, and could increase our global average temperature by 1.5°F in addition to our day-to-day human emissions. However, this effect is not included in the IPCC report issued Friday morning, which means the estimates of how Earth's climate will change are likely on the conservative side.
