Heat budget- Balance of heat between the earth and solar
radiation
Terrestrial radiation-The earth radiates energy to
the atmosphere in long wave form. This energy heats up the atmosphere from
below.
The atmosphere is indirectly heated by the earth’s
radiation.
The proportion of the incident light or radiation
that is reflected by a surface is Albedo
Difference between INSOLATION and TEMPERATURE
|
INSOLATION
|
TEMPERATURE
|
|
The energy received by the earth
|
Intensity of heat
|
|
It is Measured in calories
|
Degree of hotness
|
|
Insolation is the cause
Heat energy that makes things hotter |
It is the effect
|
Atmospheric pressure
The weight of a column of air contained in a unit
area from the mean sea level to the top of the atmosphere
The value of atmospheric pressure is 76
Pascal
Pressure gradient -The differences in atmospheric
pressure may be termed as pressure gradient
Frictional force-It is greatest at the surface and its influence
generally extends upto an elevation of 1 - 3 km
Coriolis force -It deflects the wind to the right direction in the
northern hemisphere and to the left in the southern hemisphere. It is maximum
at the poles and is absent at the equator
