Factors influencing atmospheric pressure

7 Factors influencing atmospheric pressure

Atmospheric pressure it is the weight (force) of the air exerted per unit area on the earth’s surface. It is mathematically expressed as:Pressure = Force/Area The weight of air is the vertical column exerted from the upper limit of the atmosphere to the earth’s surface which is approximately 1.034kg/cm3 over the sea level. It is …

Prominent features of Stevenson screen

weather station – features and instruments

what is Stevenson screen? A Stevenson screen or instrument shelter is a shelter or an enclosure to shield meteorological instruments against precipitation, and direct heat radiation from outside sources, while still allowing air to circulate freely around them. A Stevenson screen is a prominent feature on most weather stations. It is used to house weather …

types of temperature inversion

4 types of temperature inversion

Temperature inversion is a condition in which the temperature of the atmosphere increases with altitude in contrast to the normal decrease with altitude. When temperature inversion occurs, cold air underlies warmer air at higher altitudes. There are four kinds of temperature inversions: ground, turbulence, subsidence, and frontal. A ground inversion develops when air is cooled …

Causes and consequence of temperature inversions

Temperature inversion is a condition in which the temperature of the atmosphere increases with altitude in contrast to the normal decrease with altitude. When temperature inversion occurs, cold air underlies warmer air at higher altitudes.     Normally, temperature decreases with an increase in elevation. It is called the normal lapse rate. At times, the …

Difference between weather and climate

FULL LECTURE NOTES ON WEATHER AND CLIMATE

WEATHER Weather can be defined as the physical condition or state of the atmosphere at a particular time and place. Most weather happens in the part of the earth’s surface called the troposphere temperature, pressure, wind, humidity, and precipitation interact with each other. they influence the atmospheric conditions like the direction and velocity of the …
