The poleward-moving air is now warm and laden with moist maritime tropical air (mT); it gives rise to the warm, humid, showery climate characteristic of the Caribbean region, eastern South America, and the western Pacific island chains. easterlies blow from the poles in the east out to the west. The winds that move toward the poles between 30 and 60 latitude appear to curve to the East. When the air reaches the western extreme of the high-pressure centre, it turns poleward and then eventually returns eastward in the middle latitudes. Figure 3.10 shows only the circulation cells and winds in the northern hemisphere. Polar Easterlies: From 60-90 degrees latitude. [1] Cold air subsides at the poles creating high pressure zones, forcing an equatorward outflow of air; that outflow is then deflected westward by the Coriolis effect.

As winds are named according to the direction they originate, these winds are called prevailing westerlies. The resultant balance between the pressure force and the Coriolis force is such that, in the absence of surface friction, air moves parallel to isobars (lines of equal pressure).

Although their presence is discernible in long-term mean statistics accumulated over a hemisphere, such cells are often difficult to detect on a daily basis at any given longitude. Three prevailing wind belts are associated with these cells: the trade winds, the prevailing west winds and the polar east winds (Fig. The highest winds speeds in the north are generally during the summer. The winds are therefore called Polar Easterlies. high pressure areas in the north and south poles. This is called the geotropic wind. Please note the westerlies are also associated with the extra tropical cyclones which refer to the fact that this type of cyclone generally occurs outside of the tropics, in the middle latitudes of the planet, where the Westerlies steer the system generally from west to east. In the mean in the Northern Hemisphere, these easterlies exist to an appreciable extent only north of the Aleutian low and the Icelandic low. The effect is proportional to wind speed; that is, deflection increases as wind strengthens. Apart (In the southern hemisphere, low-pressure areas are to your right.) The polar easterlies are cold and windy, while the prevailing westerlies are hot and dry. When they move from east to west, they are called east winds. Hadley cell is a closed circulation loop, which begins at the equator with warm, moist air lifted aloft in equatorial low pressure areas (the Intertropical Convergence Zone, ITCZ) to the tropopause and carried pole ward. Satellites track winds. https://encyclopedia2.thefreedictionary.com/polar+easterlies. This makes it one of the most famous tourist destinations of the world. 3.10).
