An anabatic wind, from the Greek anabatos, verbal of anabainein meaning "moving upward", is a warm wind which blows up a steep slope or mountain side, driven by heating of the slope through insolation. [1] [2] It is also known as upslope flow. These winds typically occur during the daytime in calm sunny weather.
Berg wind, a seasonal katabatic wind blowing down the Great Escarpment from the high central plateau to the coast in South Africa. Cape Doctor , often persistent and dry south-easterly wind that blows on the South African coast from spring to late summer (September to March in the southern hemisphere).
South Africa is a sunny country, averaging 8–10 daily sunshine hours in most regions. [2] The average annual rainfall for South Africa is about 464 mm (compared to a global average of 786 mm [3]) but large and unpredictable variations are common. Overall, rainfall is greatest in the east and gradually decreases westward, with some semi-desert ...
The National Weather Service is forecasting winds up to 40 mph across much of Michigan today, which, combined with today's frosty temperatures, could mean dangerous wind chill reports. The ...
Diurnal wind system variation in the Appalachian mountain range. Mountain and valley breezes form through a process similar to sea and land breezes. During the day, the sun heats up mountain air rapidly while the valley remains relatively cooler. Convection causes it to rise, causing a valley breeze. At night, the process is reversed.
You can also approximate the wind chill with a little mental math: If the temperature is minus 13 degrees and the wind speed is 15 mph, the wind chill will be somewhere between minus 32 and minus 39.
A strong Santa Ana wind event is setting up across Southern California. A rare Particularly Dangerous Situation (PDS) alert has been issued for Los Angeles and Ventura counties.
This is the berg wind phase of the coastal low. The wind then changes abruptly to a strong, cold, south or south-westerly wind (called a “buster” if the change in wind speed is greater than 35 km/h). The buster coincides with the passage of the pressure minimum. The onshore wind gradually diminishes in intensity during the course of about a ...
