Atmospheric Pressure Factor Affecting Pressure Geography Lec 8 In this video we are going to discuss atmospheric pressure | factor affecting pressure | geography lec 8 | part 1 | barometric measurethis is the part 1 of a. Basically, atmospheric pressure has an inverse relationship with height. it decreases with an increase in altitude. the decrease of pressure is about 1 cm of mercury for every 110 m of ascent. 2. temperature. temperature is inversely proportional to pressure. it is because, with the rise in temperature, the air gets heated up and rises.
Atmospheric Pressure Terms in this set (41) the impact of pressure and wind on the landscape. atmospheric pressure indirectly affects the landscape. changes manifest primarily by changes in the wind and temperature. wind has a visible component to its activity. severe storm winds can drastically affect the landscape. the nature of the atmospheric pressure. Atmospheric pressure is the weight of the column of air at any given place and time. it is measured by means of an instrument called barometer. the units used by meteorologists for this purpose are called millibars (mb). one millibar is equal to the force of one gram on a square centimetre. a pressure of 1000 millibars is equal to the weight of. Temperature and air pressure cause expansion and shrinking of air which further results into distribution of heat and moisture in the atmosphere. in normal circumstance average air pressure at sea level is 1013.2 milibar. instrument used to measure air pressure is known as barometer. factors affecting air pressure: 1. An area of low pressure near or on the equator where the northeast trades and the southeast trades converge. characterized by calm, war, clear air. no development of clouds, the absence of wind. regions of high pressure and gentle winds at about 30 degrees north and south latitude.
