They were taken from the daily maps of surface pressure distribution over the Northern Hemisphere collected by the USWB from January 1st 1959 to December 31st 1962. Winds descend from above at the centre and thus weather becomes clear and rain less because the descending winds cause atmospheric stability. This make the sea rougher which makes the winds turn further to the centre of the developing storm.

When a tropical cyclone tops 65 knots (74 miles per hour) in the eastern Pacific, the Atlantic Ocean or the Atlantic's adjoining seas, it is known as a hurricane. While cyclones are typically regions of inclement weather, anticyclones are usually meteorologically quiet regions.Generally larger than cyclones, anticyclones exhibit persistent downward motions and yield dry stable air that may extend horizontally many hundreds of kilometres.. The average velocity of anticyclones is 30-50 km per hour.
