The strong air currents, which tend to look like wavy, striated rivers when seen on a jet stream map, form when cold air and hot air meet. The name of these unique winds comes from the direction of their origin; the westerlies run west to east while other winds run east to west. Due to the low sun angle, there is a buildup of cold air and it subsides at the poles creating surface high-pressure areas. The 2 types of LOCAL winds are sea breeze and land breeze. 3) Trade Winds (Tropical Easterlies) Rounding off the three global wind patterns, Trade Winds can be found between 0 and 30 degrees latitude in the Tropical Regions. In addition, the wind systems and the associated climate are seasonally dependent. The air moves due to uneven heating of the earth's surface between the equator and poles, which results in circulation of wind across the globe. east to west However, the wind direction is quite irregular, occasionally blowing to the west or north. The polar easterlies are located at a latitude of about 60 to 90 degrees in both hemispheres. Polar Easterlies By: Alexa, Brenna, and Amanda The End!!!

The westerlies, anti-trades, or prevailing westerlies, are prevailing winds from the west toward the east in the middle latitudes between 30 and 60 degrees latitude.They originate from the high-pressure areas in the horse latitudes and trend towards the poles and steer extratropical cyclones in this general manner. This creates an equatoward air outflow that is deflected westward by the Coriolis Effect. Apart from that, a part of the air rising from the sub polar lows that moves mainly polewards, also gradually colder and heavier, and comes down. Polar easterlies blow east to west around the North and South poles, and prevailing westerlies blow from the equator towards the poles in a westward direction. The air rises after interaction and returns to sink at the poles again. However, it is not this simple. A measure of the strength of the easterly wind between the latitudes of 55° and 70°N; the index is computed from the average sea-level pressure difference between these latitudes and is expressed as the east to west component of geostrophic wind in meters and tenths of meters per second.
