Question
(a) Multi Model Mean Surface Temperature 30 -24 18 -12 6 0612 18 24 30 Figure 1. The annual mean surface temperature across the globe computed as the average from simulations from many general circulation models (IPCC, 2013) 1. Is the spatial pattern of temperature in Figure 1 what you would expect given your knowledge of the general circulation of the atmosphere, and complicating factors influencing local temperatures (i.e. is it warm where it is supposed to be and cold where it is supposed to be)? (3 marks)Explanation / Answer
Atmospheric circulation is the large scale movement of air along with oceanic circulation through which the heat energy is redistributed on the surface of earth. Climate is influence by the general circulation of the atmosphere. The energy and moisture through middle latitudes is been carried by the global pattern of air movements, it's air masses, rising in the tropics to move downward in North. Shifts in the pattern of general circulation of air movements is responsible for change in the climate. Variance data being used as a measure of the transport properties of the Eddies.
Complicating factors influencing local temperature are -
Clouds - clouds are responsible for reflecting the rays of sun, provides shade and is responsible for keeping the Earth's surface cool. These clouds also contain water vapour and gases dissolved in it which is responsible for blocking the infrared rays of the sun trapping the heat. The effect of could cover is Confused between whether it is to cool or raise the temperature of the Earth.
*human beings - human being contribute a lot of green house gases through the emissions from factories, automobiles and smelters and these gases contribute to the global warming.
Sea - sea water absorbs the rays of Sunlight /heat and they transport it all over. Because of their potential of absorbing and distribute the heat, oceans assist to slow the procedure of temperature change in atmosphere.
