Factors that affect climate
Wind and air masses:
Global Factors that Affect Climate
As the suns UV rays hit the earth they hit is directly at the equator causing more heat. Because these rays are direct and they hit direct at one spot. For part a, the earth start to slope, in which the sun’s rays have to hit a larger areas, and have to travel further distances.
As the latitude increases, the average annual temperatures decreases. In North America particularly where we life the 3 currents that affect us are the Gulf Stream, Labrador Current and North Atlantic Drift.
The Gulf Stream Affecting the Labrador Current. Fogy Condition appear when the Gulf Stream affects the Labrador Current because, since there both different types of currents, it results in fogy conditions.
How do ocean currents affect climate?
Warm Currents: warmer climate
Cold Currents: cooler climate
The Jet Stream
What Happens to the Jet stream in the summer months, it has a more north pattern the meeting of the cold fronts are at higher latitudes. However in the winter months The jet stream is fairly lower.
Hot air rises in a clod pressure system, where as cold air takes its place.
The Canadians are effected by mostly the prevailing westerlies because, at 49th parralel is where it seperates canda and United States. And since the prevailing westeries are from 30-60 degress its will effect where we live.
As the altitude increases the temperature decreases in which it impacts the vegetation as well. In dry air the temp decreases at the rate of 1 °C for every 100 m of altitude. In moist air (when condensation begins), the temp decreases at the rate of o.6 C for every 100 m of altitude. Surface temperature equals 25
Condensations begins 900
People that live on the coast where in which they receive more moderate climate. Surface temperature equals 24 C
Condensation begins at 1200 m
When living close to a body of water you would be able to meet more moderate temperature because water take longer to heat up in the summer, and in winter it takes more longer to cool down. Continental= forms over land
Maritime= forms over water
Three types of Precipitations:
Relief Precipitation + Rain Shadow
Relief Precipitation: Relief rainfall is caused when masses of air pushed by wind are forced up the side of elevated land formations, such as large mountains. The lift of the air up the side of the mountain results in adiabatic cooling, and ultimately condensation and precipitation.
Conventional Precipitation: In convectional precipitation, unequal heating of the surface causes an air parcel to become warmer and less dense than the surrounding air. Because it is less dense, it rises. As it moves upward, it cools, and condensation with precipitation may occur. Frontal Precipitation: In this type of rainfall warm moist air encounters colder more dense air at regions we call fronts. Because the warm air is less dense since it has more energy it is forced to rise above the colder denser air. As the warm air rises it cools, water droplets within it condense and clouds form.
