Santa Ana winds and, their Bay Area cousin, the Diablo winds occur when air from a region of high pressure over the dry Great Basin region of the U.S. flows westward toward lower pressure located ...
Isotachs are drawn at these levels, which a lines of equal wind speed. They are helpful in finding maxima and minima in the wind pattern. Minima in the wind pattern aloft are favorable for tropical cyclogenesis. Maxima in the wind pattern at various levels of the atmosphere show locations of jet streams.
This outrunning occurs in a pattern where the upper level jet splits into two streams. The resultant mesoscale convective system (MCS) forms at the point of the upper level split in the wind pattern at the area of the best low-level inflow. The convection then moves east and equatorward into the warm sector, parallel to low-level thickness lines.
Diablo wind is a name that has been occasionally used for the hot, dry wind from the northeast that typically occurs in the San Francisco Bay Area of Northern California during the spring and fall.
The dominant winds are the trends in direction of wind with the highest speed over a particular point on the Earth's surface at any given time. A region's prevailing and dominant winds are the result of global patterns of movement in the Earth's atmosphere. [1] In general, winds are predominantly easterly at low latitudes globally.
The Weather Channel 9 minutes ago Winter Storm Jett To Become Northeast Bomb Cyclone With Snow, Ice, High Winds Through Sunday. Snow, ice and high winds are all threats from this weekend winter storm.
Buran (a wind which blows across eastern Asia. It is also known as Purga when over the tundra); Karakaze (strong cold mountain wind from Gunma Prefecture in Japan); East Asian Monsoon, known in China and Taiwan as meiyu (梅雨), in Korea as jangma (), and in Japan as tsuyu (梅雨) when advancing northwards in the spring and shurin (秋霖) when retreating southwards in autumn.
A Catalina eddy is rarely prolonged. As the heat over the deserts causes air to rise, the resulting pressure gradient and increase in the normal onshore winds causes the vortex to dissipate. The result is the common local weather forecast calling for "late night and early morning low clouds and fog, followed by afternoon sunshine and sea breezes."
