A map shows areas of insolation (incoming solar radiation) across the world, categorized by watts per square meter.

Average annual levels of solar radiation reaching the Earth's surface

Insolation

The map illustrates global insolation, showing variations in incoming solar radiation from the tropics to the polar regions. In the Northern Hemisphere, high insolation (220 to 280 plus watts per square meter), highlighted as dark green to dark red spans from northwestern Mexico through southern Texas, Florida, and the Caribbean, across the Atlantic to North Africa and Southwest Asia, with peaks in the eastern Sahara and Arabian Peninsula. In the Southern Hemisphere, high insolation areas stretch from East Africa to South Africa and across the Indian Ocean to most of Australia, with other high insolation zones in the Central Pacific and south-central South America. Middle insolation values (120 to 219 watts per square meter), highlighted as light blue to green, are found between 50 degrees north and 50 degrees south latitude, excluding high insolation regions. Low insolation areas (80 to 119 watts per square meter), highlighted as blue to light blue, are located north of the 50-degree lines to the poles in North America, the North Atlantic, and Eurasia, and around the Southern Ocean in Antarctica. The lowest insolation values (less than 80 watts per square meter), highlighted as dark blue, are in the ocean east of northern Greenland.

A world map depicts seasonal precipitation from October to March across various regions globally, measured in inches.

Average precipitation between October 1 and March 31

Seasonal Precipitation, October to March

Areas with the least precipitation, ranging from 0 to 5 inches, are marked in lightest blue and include much of northern Canada (Brooks Range, Victoria Island, Baffin Island), Greenland, the Arctic regions, and the western United States (Colorado Plateau, Wyoming, North and South Dakota, Mexico), as well as central Asia (Iran, Pakistan, Part of India, Kazakhstan, Uzbekistan, China, Mongolia, Saudi Arabia, Yemen), parts of the Middle East, northern Africa (Algeria, Libya, Niger, Chad, Sudan, Mauritania, Mali), and interior regions of Australia (South Australia, Perth).Regions with 5 to 10 inches of precipitation, shown in light blue, cover parts of central Canada (Saskatchewan, Manitoba), parts of the central United States (Montana, Idaho, Utah, Arizona, New Mexico), central Europe (France, Germany, Poland, Belarus), northern Africa (Morocco, Tunisia), central Asia (Turkmenistan, Kyrgyzstan), southern Africa (Namibia, Botswana), and southern Australia (Victoria, Tasmania).Areas receiving 10 to 20 inches, highlighted in medium blue, include the central United States (Nebraska, Kansas, Oklahoma), parts of South America (central Brazil, parts of Argentina), northern Europe (United Kingdom, Denmark, southern Sweden), eastern Europe (Ukraine, Romania), the eastern parts of South Africa, western and southern China, northern India, and coastal regions of New Zealand.Regions with 20 to 40 inches, marked in blue, cover the southeastern United States (Louisiana, Mississippi, Alabama, Georgia), the Amazon Basin in South America, parts of central Africa (Congo, Zambia), western Europe (Portugal, Spain, Italy), the Indian subcontinent (southern India, Bangladesh), and eastern Australia (New South Wales, Queensland).Darker blue areas, indicating 40 to 80 inches of precipitation, include the Pacific Northwest of the United States (Washington, Oregon), parts of western South America (Andes regions in Colombia, Ecuador, Peru, Brazil), Southeast Asia (Vietnam, Sri Lanka), parts of Indonesia (Sumatra, Borneo), Malaysia, and the island of New Guinea.The highest precipitation, over 80 inches, represented in darkest blue, is found in the Pacific Northwest of the United States (northern California, Oregon, Washington), parts of Southeast Asia (Malaysia, western Philippines), and Papua New Guinea.
