In meteorology, wind (Latin ventus for blowing) is a directional, stronger movement of air in the earth's atmosphere as one of the many factors in the weather or in the long-term weather patterns of the climate. The main cause of wind is spatial differences in air pressure distribution. Air particles move from the area with the higher air pressure (the high pressure area) to the area with the lower air pressure (the low pressure area) until the air pressure is equalised. The greater the difference between the air pressure values, the more violently the air masses flow into the area with the lower air pressure and the stronger the wind resulting from the air movement. Wind speeds of 62 kilometres per hour or more are referred to as a storm (wind force 8) and wind speeds of 118 kilometres per hour or more are referred to as a hurricane (wind force 12 = maximum). The wind direction is usually given in the form of a compass direction from which the wind is coming.
