UNIT 9—LESSON 1

GENERAL ASPECTS OF TROPICAL ANALYSIS

OVERVIEW 

Recognize the general principles of tropical analysis.

OUTLINE

Weather differences within the tropics

Weather element representativeness

GENERAL ASPECTS OF TROPICAL ANALYSIS

When you examine the weather of the tropics, one thing stands out—the heat. As Earth orbits around the Sun, the Sun’s most direct rays shift northward and southward between 23 1/2°N and 23 1/2°S. The heat that accompanies these latitudinal shifts lags behind the Sun by 1 to 2 months. This is borne out by the fact that in the midlatitudes, July and August temperatures are warmer than those of June (month of the summer solstice) and January and February temperatures are colder than those of December (month of the winter solstice). This effect is not nearly as evident in the tropics. The tropics remain warm throughout the year. Even when the Sun’s heaviest concentration of rays is over the Southern Hemisphere (winter in the Northern Hemisphere) the Northern Hemisphere tropical latitudes remain hot.

The Tropic of Cancer and Tropic of Capricorn are geographical boundaries assigned to the tropics based on Earth’s position in relation to the Sun. Another set of tropical latitude boundaries, 30°N and 30°S, were assigned based on the tri-cellular theory that we discussed earlier. Latitude boundaries permit easy reference, but you must remember that tropical air is not confined to tropical latitudes, just as polar air is not confined to polar latitudes. For the most part, as far as weather is concerned, these boundaries are simply borders that are crossed with great regularity. In reality, the tropical weather belt expands and contracts as it moves north and south following the Sun. It is wider over continents than over the oceans. Since there are no specific latitude boundaries assigned in tropical meteorology, another set of dividing lines is used. We use the winds of the middle troposphere. More specifically, the poleward boundaries are roughly where the tropical easterly winds of the mid-troposphere give way to the midlatitude westerlies. 

Learning Objective: Recognize the tropics, the representativeness of weather elements, and what drives our approach in analyzing the weather over this region.
