Meteorological images of the month -- August 2012

By: Stu Ostro , 3:12 AM GMT on September 04, 2012

Here are my choices for top meteorological images of the month for August 2012.

Even though just a simple line graph, this is arguably the most stunning one. It shows the 2007 satellite-era record for low Arctic sea ice extent being shattered.

In the first part of the month, there was a cyclone in the Arctic which tied the Northern Hemisphere record low 500 millibar height (daily mean in reanalysis data going back to 1948) for that time of year (so early in the pre-autumn season).

A line of intense thunderstorms blasting across Chicago. Learning from last year’s tragedy in Indianapolis, Lollapalooza officials ordered concertgoers to evacuate before the storms arrived.

Moisture associated with the second highest calendar-day rainfall total on record in Las Vegas is juxtaposed to dry air which looks like a gigantic brown bear claw.

An exceptionally strong cyclone for midsummer spirals toward the Olympics.

Throughout its life, Isaac was huge in size, which was important in the nature and magnitude of its impacts on and near the U.S. Gulf Coast. Here it dominates the eastern Caribbean and western tropical Atlantic. Early morning sunlight is illuminating dust, representative of dry air that was also characteristic of Isaac’s life, helping to limit its winds from becoming more intense than they were.

A strong, hot, dry ridge of high pressure to the north of Isaac blocked the hurricane and slowed its movement, prolonging its impacts. Here, Isaac, having weakened to a tropical depression, pokes northward into that ridge.

Hi there! Quick question that’s totally off topic. Do you know how to make your browsing extremely high? My blog looks weird when browsing from my SMA Xaverius 1 Sekolah Terbaik di Palembang. I’m trying to find a template or plugin that might be able to fix this issue. If you have any recommendations, please share. Many thanks!
