Meteorological images of the month -- August 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).

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.
