Top 10 me­te­o­rol­o­gy facts

In Venezuela. Catatumbo lightning is an atmospheric phenomenon in Venezuela. It occurs only over the mouth of the Catatumbo River where it empties into Lake Maracaibo. The phenomenon is characterized by almost continuous lightning and occurs during 260 nights a year, 10 hours per day and up to 280 times per hour. It has been known for centuries as the Lighthouse of Maracaibo, since it is visible for miles around Lake Maracaibo

Southern foothills of the Himalayas. Mawsynram village in northeast India has the highest average annual total precipitation in the world (11,872 mm = 467.4 in). There, hot and moist air from the south of India approaches Himalayas. It rises up, cools and loses water.

Lenticular clouds are stationary clouds that form in the troposphere, typically in perpendicular alignment to the wind direction. They are often comparable in appearance to a lens or saucer. Because of their unique appearance, they have been brought forward as an explanation for some unidentified flying object (UFO) sightings.

Jet stream helps. The location of the jet stream is extremely important for aviation. Commercial use of the jet stream began on 18 November 1952, when Pan Am flew from Tokyo to Honolulu at an altitude of 7,600 metres, cutting the trip time by over one-third.

−89.2°C (−128.6°F). Vostok Station is a Russian research station in inland Princess Elizabeth Land, Antarctica. Founded by the Soviet Union in 1957, the station lies at the southern Pole of Cold, with the lowest reliably measured natural temperature on Earth of −89.2°C (−128.6°F; 184.0 K)

White. Albedo in Latin is simply "whiteness". It is the reflecting power of a surface - the ratio of reflected radiation from the surface to incident radiation upon it.

Chinook is claimed to mean "ice-eater", as it can make snow one foot deep vanish in one day. The snow partly melts and partly evaporates in the dry wind. The greatest recorded temperature change in 24 hours was caused by Chinook winds on 15 January 1972, in Loma, Montana; the temperature rose from −48 to +9 °C (−54 to +49 °F)

Sunny. These puffy clouds are called "fair weather cumulus". They have little vertical extent and do not give precipitation. When they appear in a clear sky, they are an indicator of pleasant weather for the next several hours.

Warm air passes over a cool continent. Advection fog is formed by the passage of warm and moist air over a colder water surface. The air gets cooled and loses water. This kind of fog is common at sea whenever cold and warm ocean currents are in close proximity.

Iridescence is the phenomenon of certain surfaces that appear to gradually change colour as the angle of view or the angle of illumination changes. Examples of iridescence include soap bubbles, butterfly wings and sea shells, as well as certain minerals. It is often created by structural coloration (microstructures that interfere with light).
