The chief source of atmospheric heat is a. incoming solar radiation b. infrared radiation from the earth itself
The chief source of atmospheric heat is
a. incoming solar radiation
b. infrared radiation from the earth itself
c. ultraviolet radiation absorbed by ozone
d. ultraviolet radiation absorbed by clouds
Solutions
Expert Solution
The solar radiation coming from the sun will not directly strike the earth surface. When the light rays reaches to the atmosphere, the infrared radiation is absorbed by the gases present in the atmosphere. Then theses gases reflects 25% of infrared radiation and remaining radiation will heat up the atmosphere.
Thus, option (b) is correct.
Since incoming solar radiation will not directly fall on the atmosphere of earth, thus it is not a chief source of atmospheric heat. Thus, option (a) is wrong.
Ultraviolet radiation does not fall on the troposphere because these are absorbed by the ozone present in the stratosphere. Since atmosphere is present in troposphere, ultraviolet radiation is not a chief source of atmospheric heat. Thus, option (c) and (d) are wrong.
Thus, option (b) is correct.

In tropical regions less energy is emitted by the earth as
infrared radiation than is absorbed as solar radiation averaged
over the year. Explain briefly why tropical regions do not
continually get warmer year after year after year.

For a particular location the average net solar radiation is
6.65 MJ m-2d-1, the soil heat flux is
0.1Rn, the atmospheric temperature is 20⁰ C, the water
surface temperature is 18⁰ C, and a pressure gage height of 2 m.
Since this area is rather arid, the dryness coefficient is a little
larger than normal, with a value of 1.33. Determine the open water
evaporation rate in mm/day using the Priestley-Taylor method.

Problem 6. In space, thermal equilibrium is achieved
when incoming radiation (e.g. from the Sun) is balanced against
outgoing radiation (e.g. from the surface of Earth). The
equilibrium achieved is a dynamic one, because there is still a net
flow of heat in and out of the system, and the Sun and Earth never
reach the same temperature (thankfully) because much of the
radiation leaves the system.

Question 2. A family in Eastern Australia installs solar panels
to run an air-source heat pump to heat their swimming pool. The
panels produce a total of around 6 kW of electricity during the
day. The heat pump draws 5 kW of electricity and delivers 23 kW of
heating to the pool.
a) The pool contains 40,000 litres of water. When the heat pump
is running, estimate the rate at which the temperature of the water
in the pool rises,...
