Sea-surface temperature anomalies during El Niño. The most intense warming (2 to 2.25 degrees Celsius, dark brown) occurs off the coast of South America. Cooler areas (negative 2.25 to negative 2 degrees Celsius, dark blue) are in the Arctic Ocean.

A composite of sea-surface temperature anomalies during El Niño from November to March during the following years: 1958, 1966, 1973, 1983, 1987, 1992, 1996, and 1998. When sea-surface temperatures in the tropical eastern Pacific rise well above normal, it is known as an El Niño event.

A map displays the average distribution of dew point temperatures across North America in January, using different colors to represent various temperature ranges.

Average January dew points for the contiguous United States

Average Distribution of Dew Points, January (U.S.)

Less than 20 degrees Fahrenheit (Red): Covers most of the United States, excluding the southern and coastal areas, extending into Canada and northern Mexico. 20 degrees Fahrenheit (Blue): North Texas, Oklahoma, Arkansas, Tennessee, North Carolina, Kentucky, eastern Washington, Eastern Oregon, Idaho, and some part of Utah. 30 degrees Fahrenheit (Purple): Most of California along the coast, western Oregon, western Washington, central Texas, northern Louisiana, Alabama, Georgia, and South Coalinga. 40 degrees Fahrenheit (Orange): Covers parts of southern Texas, Louisiana, south of Georgia and north of Florida. 50 degrees Fahrenheit (Yellow): Southcentral region of Florida. 55 degrees Fahrenheit (Green): Restricted to the southern tip of Florida.

A map illustrates global tropical cyclone zones, indicating areas where tropical typhoons, cyclones, and hurricanes form.

Areas of the world affected by tropical cyclones. In the Americas, tropical cyclones are known as hurricanes; in the western Pacific Ocean, they are known as typhoons; and in the Indian Ocean, they are known as cyclones.

Tropical Cyclone Zones

Areas shaded in blue represent tropical cyclone zones, predominantly found over parts of the tropical or subtropical Atlantic, Indian, western Pacific, and eastern Pacific oceans. These storms form in specific regions: Atlantic Ocean: Including the Gulf of Mexico, the Caribbean Sea, and extending towards the eastern United States and parts of Central America. Indian Ocean: Covering areas around the Arabian Sea and the Bay of Bengal. Western Pacific Ocean: Extending from the Philippines, Vietnam, and Cambodia to the eastern coasts of China and Japan. Eastern Pacific Ocean: Including the coastal regions of Mexico and parts of Central America. Southern Hemisphere: Affecting regions around Madagascar, parts of Australia, the South Pacific islands (Fiji, Samoa), and the eastern coasts of Africa.

A map highlights the average distribution of dew point temperatures in July across North America.

Average July dew points for the contiguous United States

Average Distribution of Dew Points, July (U.S.)

The lightest shade of green represents a dew point of 20 degrees Fahrenheit, seen in parts of the western United States. The light shade of green, indicating a dew point of 30 degrees Fahrenheit, covers areas such as parts of Idaho, Wyoming, Nevada, and Utah. Moving southward, the green shade representing 40 degrees Fahrenheit is visible in regions including parts of the mostly western United States, such as Montana, Washington, Oregon, New Mexico, and Arizona. The medium green shade represents the 50 degrees Fahrenheit range and is seen in the northern Midwest, including parts of North Dakota. The darker shade of green represents higher dew points, with 55 degrees Fahrenheit covering regions like South Dakota, central parts of Wisconsin, Chicago, and New York. The green color represents 60 degrees Fahrenheit and is widespread in the central to eastern United States, covering areas like Dallas, Texas, Iowa, Illinois, Virginia, and Washington D.C. The brown color represents 65 degrees Fahrenheit and is concentrated in the southeastern United States, covering regions such as Tennessee, Georgia, and the Carolinas. The darkest shade of brown represents dew points of more than 70 degrees Fahrenheit, seen in the Gulf Coast states, including Louisiana, Mississippi, Houston, Florida, and Miami.

The map shows urban air quality in terms of micrograms of particulate matter per cubic meter of air. For the purposes of this description, the five categories on the map are simplified to less 80 micrograms per cubic meter; between 80 and 200 micrograms per cubic meter; and more than 200 micrograms per cubic meter. In North America, there are several areas with multiple locations where air quality is less than 80 micrograms: in Canada, near Vancouver, British Columbia; in Alberta; and in southern Ontario and Quebec near the Great Lakes and St. Lawrence River. In the United States, areas with air pollution in this range occur in mainly in California and in the Midwest and Northeast. A few scattered locations in Mexico, Central America, and the Caribbean (Jamaica) also have pollution in this range. In South America, air quality less than 80 micrograms per cubic meter occurs in widely scattered locations, such as Caracas, Venezuela; Colombia; Ecuador; Bolivia; northern and central Chile; Buenos Aires, Argentina; and north of Rio de Janeiro, Brazil. Most of Western and Central Europe have air pollution of less than 80 micrograms per cubic meter. Exceptions include Ireland, Portugal, and Scandinavia. (In Russia, air pollution is at this level in Moscow, but east of the Urals in Siberia, there are also sites that are more polluted—between 80 and 200 micrograms. Africa has relatively little air pollution of this type, areas less than 80 micrograms include Liberia, Tanzania, Madagascar, and South Africa (the area around Johannesburg). In Southwest Asia, Turkey, Lebanon, Israel, and Cyprus have multiple sites less than 80 micrograms per cubic meter. However, Iran and the Persian Gulf states (Bahrain, Qatar, the United Arab Emirates) have multiple sites between 80 and 200 micrograms, and Iraq and Bahrain have sites that are higher than 200 micrograms. Apart from Kabul, Afghanistan, which is higher than 200 micrograms per cubic meter, there are no countries in Central Asia that have poor urban air quality according to the criteria used here. In northern Pakistan, India, and Bangladesh, there are cities with poor urban air quality—ranging from 80 to more than 200 micrograms per cubic meter. In southern India, Sri Lanka, and Nepal, pollution levels range from below 80 up to 200 micrograms per cubic meter. In Southeast Asia, pollution in Myanmar, Thailand, Laos, Vietnam, and Indonesia is generally less than 80 micrograms, except in the northern Philippines, where it is between 80 and 200. In the cities of southern and western China, pollution is less than 80 micrograms per cubic meter, except in far western Urumqi, which is between 80 and 200 micrograms. In eastern and northern China urban air pollution increases to between 80 and 200 micrograms. Mongolia has a few locations less than 80 micrograms per cubic meter and others between 80 and 200 micrograms. South Korea has numerous cities with pollution less than 80, whereas in Japan, Tokyo is the only city in this category. In Oceania, only New Zealand is identified as having poor urban air quality, with two locations on the South Island less than 80 micrograms per cubic meter.

Ambient (outdoor) air pollution levels represented by annual mean concentration of particulate matter smaller than 10 (PM₁₀), for cities of the world with more than 100,000 inhabitants
