Study the article above. Why is the weather of the UK so changeable? The geographic location of the Hadley circulation moves north and south with the seasons; however, the equatorial trough lags behind for about two months owing to the thermal inertia of Earths surface. Heavy rainfall occurs with lightning and thunder. This occurs due to the convergence of different air masses with different temperatures, density, and humidity. This cooling turns the water vapor to condense, and as the vapor condenses, the cloud is formed. The rain or precipitation flows into rivers and streams, and these rivers and streams eventually flow into the sea where the cycle begins again. This persistent circulation mechanism transports heat from the latitudes of greatest solar insolation to the latitudes of the subtropical ridges. Because these trade winds converge near the equator, the tropical rain belt is known to meteorologists as the Inter-tropical Convergence Zone. It also happens on a small scale within individual storms. Protection of cold environments as wilderness areas. How have plants adapted to cold environments? Locally, these ridges are given such names as the Bermuda High, the Azores High, and the North Pacific High. . Extratropical cyclones have three stages of expansion: the developing stage, in which an undulating wave develops along the front; the mature stage, in which sinking cold air sweeps equatorward west of the surface low-pressure centre and ascending warm air moves poleward east of the cyclone; and the occluded stage, in which the warm air is entrained within and moved above the polar air and becomes separated from the source region of the tropical air. There is a moister climate on windward sides of slopes while the lee side of a mountainous area is much drier. The power of Earths spin to turn flowing air is known as the Coriolis Effect. III. Summarize the impacts of the convectional storms in Kansas in a list. Stage 1. When warm air reaches the coolest layer of the atmosphere; then it condenses and forms cumulonimbus clouds. On the poleward side of the front, the air is cold and more dense; equatorward of the front, the air is warmer and more buoyant.
