Question

Briefly describe how winds are formed

Answer 1

As the earth is affected by an unequally of heat energy from the sun, the state of the air differentiate between different regions. Warm air expands and rises up while cold air condenses and sinks, hence resulting the flow of air and forms wind. In meteorology, unless otherwise specified, wind means the horizontal motion of airflow and signifies with wind direction and wind speed (wind force). Wind direction indicates the direction from which the wind is blowing and is usually reported to one of the 16 points of the compass (N, NE, etc.) or 360° with reference to true north. Wind speed indicates the rate of the motion of the air on a unit of time and is usually measured in meter per second (m/s), kilometer per hour (km/h) or knots.
