Nevertheless, the prevailing wind at the majority of sites in Britain lies somewhere between west and south. ; The direction can be specified either as the number of degrees clockwise from true north, or as one of the 8 or 16 compass points. It also lets you minimize the area thats subject to faster energy swings from the rising or setting sun. [16] Due to the low sun angle, cold air builds up and subsides at the pole creating surface high-pressure areas, forcing an outflow of air toward the equator;[17] that outflow is deflected westward by the Coriolis effect. DO NOT use for the preservation of life or property! Radar shows an accurate and real-time map of rain andsnow. Differential heating from the Sun between the land which is quite cool and the ocean which is relatively warm causes areas of low pressure to develop over land. variability, Max, [25], In South America, the Andes mountain range blocks Pacific moisture that arrives in that continent, resulting in a desertlike climate just downwind across western Argentina. The dominant winds are the trends in direction of wind with the highest speed over a particular point on the Earth's surface at any given time. National Center for Atmospheric Research (2006). Many of these sites have more than twenty five years of data. From early November to mid-March, the lighter and drier winds of the northeast monsoon bring variable cloudiness, infrequent precipitation, and lower humidity.

Next, select your state, then select the .gif file for the location and month(s) of the year you are interested in. The warm air is less dense and so it rises. Prevailing winds are the predominant surface winds in an area. In areas where there is rugged topography that significantly interrupts the environmental wind flow, the wind can change direction and accelerate parallel to the wind obstruction. The arrows indicate the direction of airflow. In the mid-latitudes, westerly winds are dominant, and their strength is largely determined by the polar cyclone. between 35 and 65 degrees latitude), which blow in areas poleward of the high pressure area known as the subtropical ridge in the horse latitudes. An interesting example is the Tibetan Plateau, where the monsoon creates steady strong winds from December to April, and calm winds from June to October. Against prevailing westerly . The simulated weather data have a spatial resolution of approximately 30 km and may not reproduce all local weather effects, such as thunderstorms, local winds, or tornadoes, and local differences as they occur in urban, mountainous, or coastal areas.
