Venus revolves or orbits around the Sun once every 0.615 Earth years, or once every 224.7 Earth days. Venus travels at an average speed of 78,341 miles per hour or 126,077 kilometers per hour in its orbit around the Sun.
5 Sol-Air Temperature Sol-air temperature (Tsol) is the fictitious temperature of the outdoor air which, in the absence of radiative exchanges on the outer surface of the roof or wall, would give the same rate of heat transfer (Q) through the wall or roof as the actual combined heat transfer mechanism between the sun, the surface of the roof or wall, the outdoor air and the surroundings.
Continental Polar air masses (cP) are air masses that are cold and dry due to their continental source region. Continental polar air masses that affect North America form over interior Canada.n air mass originating over northern Siberia in winter may be indicated as cA. The stability of an air mass may be shown using a third letter, either k (air mass colder than the surface below it) or w (air mass warmer than the surface below it).
