Where does the phenomenon known as the Lighthouse of Maracaibo occurs?
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
What is this?
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.
Which continent has the lowest precipitation rate?
Antarctica is technically a desert, averaging just 166 mm (6.5 in) of precipitation per year. Only some fringe coastal areas have a tundra climate with a short summer, averaging above freezing, and much higher precipitation.
What is the name given to the local dry wind in the Rocky Mountains?
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)
What clouds produce a drizzle?
Stratus. The term stratus is used to describe flat, hazy, featureless clouds of low altitude varying in color from dark gray to nearly white. Stratus clouds may produce a light drizzle or a small amount of snow. These clouds are essentially above-ground fog formed either through the lifting of morning fog or through cold air moving at low altitudes over a region.
In 2002, Steve Fosset became the first person to fly around the world in a hot air balloon. Where did he start and land?
In Australia. Fossett chose a southern hemisphere route to take advantage of prevailing easterly winds and the lack of mountain ranges. His path after leaving Australia was straight across the South Pacific, past Easter Islands, and over the southern tip of South America.
Saffir-Simpson scale is used to measure ...
Hurricane force. Officially, the Saffir–Simpson hurricane wind scale is used only to describe hurricanes forming in the Atlantic Ocean and northern Pacific Ocean east of the International Date Line. Other areas use different scales to label these storms, which are called "cyclones" or "typhoons", depending on the area.
What is the name of this phenomenon?
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).
What is the name of this cloud?
Arcus clouds most frequently form along the leading edge or "gust fronts" of thunderstorm outflow; some of the most dramatic arcus formations mark the gust fronts of derecho-producing convective systems. Roll clouds also may arise in the absence of thunderstorms, forming along the shallow cold air currents of some sea breeze boundaries and cold fronts.
