| A second region of high pressure exists over the poles, where the descending air spreads outward to form the polar easterlies. |
|
| Unlike westerlies and trade winds, the polar easterlies are not a global wind belt. |
|
| The polar front forms where the polar easterlies and the prevailing westerlies converge. |
|
| Prevailing westerlies occur between the polar easterlies and trade winds. |
|
| At the mid-latitudes, the winds are called the westerlies, and at the highest latitudes, the winds are called the polar easterlies. |
|
| The British Isles lie at the convergence zone between the warm southwest antitrades and the cold polar easterlies. |
|
| As in the middle latitudes, the presence of major landmasses, notably in the Northern Hemisphere, results in significant variations in these polar easterlies. |
|
| The winds over Antarctica are called the polar easterlies where winds blow from the east to the west. |
|
| Wind patterns must have included strong polar easterlies at high northern latitudes, prevailing westerlies at midlatitudes, and northeast trade winds in the tropics. |
