Global Winds | The combination of convection cells found at every 30 degrees latitude and the Coriolis Effect producing patterns of air circulation. |
Polar Easterlies | Prevailing winds that blow from east to west between 60 degrees and 90 degrees latitude in both hemispheres |
Prevailing Westerlies | Prevailing winds that blow from west to east between 30 degrees and 60 degrees latitude in both hemispheres |
Trade Winds | Prevailing winds that blow northeast from 30 degrees north to the equator and 30 degrees south to the equator |
Doldrums | A calm area of very weak winds where trade winds of the Northern and Southern hemisphere meet, somewhere along the equator |
Horse Latitudes | An unusually calm area of sinking high pressure at about 30 degrees north and 30 degrees south latitude |
Jet Stream | A narrow belt of strong winds that blow in the upper troposphere and lower stratosphere |
