Trends Of Weather Patterns Question 1 The global patterns of atmospheric heating as well as circulation are usually best describable as the air circulation over the earth. This circulation is largely caused by uneven heating of the exterior and the powered patterns of precipitation. The worldwide circulation of atmosphere usually shifts the cold air starting from the high latitudes into the route of low latitudes, and in the route of low latitudes. In addition, the warm air comes from low latitudes heading to the route of high latitudes (Miller & Spoolman, 2009). The air ascends beyond the surface and moves away close to the top troposphere as well as moving to the pole region.
