- Tropical wet and dry climate exists in much of northwestern, central, and eastern India. This section extends into the northern half of Sri Lanka. The northern side of this section meets boundaries with semiarid and humid subtropical climates. The eastern side of this section meets boundaries with tropical wet climate and the Bay of Bengal. The southern side of this section meets boundaries with the Indian Ocean and tropical wet climate. The western side of this section meets boundaries with the Indian Ocean, semiarid, and tropical wet climates.
- Another section of tropical wet and dry climates exists in western and central Myanmar. This northern and eastern sides of this section meet a boundary with humid subtropical climate. The western side of this section meets a boundary with tropical wet climate.
- Areas shaded in dark green represent tropical wet climate. Tropical wet and dry climate exists in two areas on the map.
- Tropical wet climate exists in correlation with the Western Ghats in western India. This section extends into the southern half of Sri Lanka. The eastern side of this section meets a boundary with the Arabian Sea. The northern side of this section meets a boundary with tropical wet and dry climate. The eastern side of this section meets boundaries with tropical wet and dry and semiarid climates.
- Another section of tropical wet climate exists on the southern coast of Bangladesh and extends southeastward along the western coast of Myanmar. The northern side of this section meets a boundary with humid subtropical climate. The southern and western sides of this section meet a boundary with the Bay of Bengal. The eastern side of this section meets a boundary with tropical wet and dry climate.
Summer and Winter Monsoon Winds and Rainfall
Summer Monsoon Winds and Rainfall
The map is titled Summer Monsoon Winds and Rainfall. The map displays the rainfall and direction of wind on a map of India and Sri Lanka. India is central in the map. A map key exists on the left side of the map, which explains the colors used the amount of rainfall in inches. A compass rose does not exist on this map. It is assumed that the cardinal direction of north is toward the top of the map, west is to the left of the map, east is to the right of the map, and south is toward the bottom of the map.
- White arrows are used to show the wind direction during the summer monsoon.
- On the western coast of India, there are four white arrows all pointing northward and eastward.
- There are two arrows in south central India that point northward and eastward.
- There are two arrows in the east coast of India that point more northward than eastward.
- There are three arrows in north central India that point northward and westward.
- The rainfall amounts in inches are displayed in India and Sri Lanka using various shades of purple. The darkest purple color represents more than forty inches of rain and the lightest purple color represents less than five inches of rain.
- In northern India, from left to right, the rainfall amounts go from the lowest to the highest in order from west to east. Most of northwestern India receives less than five inches of rainfall. Heading eastward, the color purple darkens slightly, and that area receives five-to-ten inches of rain. Continuing eastward, the color purple darkens again and that area receives ten-to-twenty inches of rain. Continuing eastward, the color purple darkens again and that area receives twenty-to-forty inches of rain. The areas of northeastern India and parts of central India are shaded the darkest color purple and receive more than forty inches of rain.
- In southern India, the darkest color purple is found in correlation with the Western Ghats. This section receives more than forty inches of rain. Moving eastward, the central area of southcentral India receives twenty-to-forty inches of rain. There are two isolated areas in central and southeastern India that receive only ten-to-twenty inches of rain. All of these sections are colored the shade of purple that indicated the rainfall amount.
- In Sri Lanka, the northern half of the island receives twenty-to-forty inches of rain and the southern half receives more than forty inches of rain. These two sections are colored the shade of purple that indicates the rainfall amount.
Winter Monsoon Winds and Rainfall
- The map is titled Winter Monsoon Winds and Rainfall. The map displays the rainfall and direction of wind on a map of India and Sri Lanka. India is central in the map. A map key exists on the left side of the map, which explains the colors used the amount of rainfall in inches. A compass rose does not exist on this map. It is assumed that the cardinal direction of north is toward the top of the map, west is to the left of the map, east is to the right of the map, and south is toward the bottom of the map.
- White arrows are used to show the wind direction during the winter monsoon.
- There are five arrows all located in northeastern India. All five of these arrows point in a southwestern direction.
- The rainfall amounts in inches are displayed in India and Sri Lanka, using various shades of purple. The darkest purple color represents more than forty inches of rain and the lightest purple color represents less than five inches of rain.
- A small section of the lightest color purple exists in the most northern portion of India. This section receives less than five inches of rain.
- A small section of western India near Pakistan receives five-to-ten inches of rain. It is colored a slightly darker shade of purple than the lowest shade.
- The majority of the map is colored the lightest shade of purple and receives five-to-ten inches of rain.
- In southern India, the most southern section and part of the southeastern coastline are shaded the color purple that correlates with ten-to-twenty inches of rain. Directly above this section, there is a slightly lighter shade of purple that indicates five-to-ten inches or rain.
- All of Sri Lanka is shaded in the second darkest shade of purple. Sri Lanka receives twenty-to-forty inches of rainfall.
- From northwest India extending to northeast India, there is a band of the second lightest shade of purple that indicates ten-to-twenty inches of rain. Throughout this band, there are two smaller sections that are shaded darker purple and the second darkest purple. These sections receive ten-to-twenty inches of rain or twenty-to-forty inches of rain. One of these sections is toward the northwest and the other is located in the northeast. The section in the northeast has the second darkest shade of purple in the center.
- Nowhere on the map is the darkest shade of purple. No location receives more than forty inches of rain.
