Hole in the skyThis image taken on June 5th 2012 shows what you could call the opposite of a hurricane. NASA’s MODIS aboard the Aqua satellite took this image of a 1000km diameter hole in a blanket of marine stratocumulus clouds near Tasmania. Looking at the hole from above, it almost appears to plunge down.This rare sight was caused by a high pressure weather system which usually brings clear skies. (low pressure areas in contrast are a forebode of storms and cloudy weather) In general wind blows away from high pressure areas, thus the air pulls downwards. The sinking air in turn warms which makes it difficult for clouds to form. The shape of the high pressure system actually matches the hole.-OW-Image: NASA MODIS (Moderate Resolution Imaging Spectroradiometer).References:http://earthobservatory.nasa.gov/IOTD/view.php?id=78208 -- source link
