How does temprature influence the horizontal distribution of air pressure? Explain briefly .
Answers
Answer:
Distribution of temperature is not similar at all the places on the Earth. Because of difference in temperature, air pressure also varies immensely.
Weight of air is known as air pressure. Air is a composition of various gases therefore it has specific weight. Weight of air on any unit of area on Earth is known as air pressure while it is represented in Millibar unit. Air expands in summer due to high temperature and in winter it shrinks due to low temperature.
i) Rays of sun fall vertically in this region whole the yearlong and because of this temperature is high which creates low pressure.
(ii) Owing to high temperature, evaporation process is also very fast while large number of water vapours decreases the weight and density of air resulting in reduction of air pressure.
