What are the global winds? Global winds or Planetary winds are large body air masses created mainly as a result of the earths rotation, the shape of the earth and the suns heating power. Global winds are caused by the combination of pressure belts and the Coriolis effect. Generally, winds are named based on the direction in …
What is Atmospheric Temperature? Atmospheric temperature is the temperature of the earths atmosphere measured at different levels. This is dependent on many factors such as clouds, latitude, incoming radiation, land surface, air, altitude, ocean currents, and water surface, etc. The reason for the warmth and the coldness of the atmosphere is due …
Air pressure is measured with an instrument called a mercury barometer or the aneroid barometer. On maps, places of equal atmospheric pressure are joined together by lines called ISOBARS. Meaning of Atmospheric Pressure Atmospheric pressure is the weight of the volume of air which extends from the ground surface to the outermost …
Atmospheric circulation definition Atmospheric circulation is referred to as the large scale movement of air at levels of the atmosphere by which heat is circulated on the surface of the Earth; this is also referred to as the different amount of insolation absorbed by the earth which causes differential heating of the …
Tornadoes Facts Tornadoes are the most violent of all the storms, capable of picking up trees, cars, roofs and walls of buildings. Tornadoes generally occur in middle latitudes. They are very small in size and of short duration which makes weather prediction difficult. Tornados funnel can have the size of 90-460m in …
Definition of tropical cyclones Tropical cyclones are violent storms that originate over oceans in tropical areas and move over to the coastal areas bringing about the large scale of destruction caused by violent winds, very heavy rainfall and storm surges. This is known as one of the most devastating natural disasters in …
Definition of anticyclones Anticyclone which is commonly known as high is a wind system which has highest air pressure at the centre and lowest at the outer margin and winds blow from the centre outward in clockwise direction in the northern hemisphere and anticlockwise in the southern hemisphere; anticyclones are high-pressure systems …
A source of water simply refers to a point where water can be found. Source of water does not necessarily mean the water must be clean or pure. It simply means there is water that can be found there; be it dirty water or clean water). There are different sources of water …
