The Diablo wind is created by the combination of strong inland high pressure at the surface, strongly sinking air aloft, and lower pressure off the California coast. The air descending from aloft as well as from the Coast Ranges compresses as it sinks to sea level where it warms as much as 20 °F (11 °C), and loses relative humidity.
Pressure-wind relations can be used when information is incomplete, forcing forecasters to rely on the Dvorak Technique. [6] Some storms may have particularly high or low pressures that do not match with their wind speed. For example, Hurricane Sandy had a lower pressure than expected with its associated wind speed.

Here’s a cheat sheet, from temps to wind speed. Shaun Goodwin. ... or a multitude of other weather outlets that perform a similar function. In that case, you’ll most often deal with the ...
= wind speed (m/s) The constants in these formulas are deduced from empirical data. Factoring in water depth, wind fetch, and storm duration complicates the equations considerably. However, the application of dimensionless values facilitates the identification of patterns for all these variables. The dimensionless parameters employed are:
Diablo, a Spanish word which translates to devil in English, is also the name of a mountain in Contra Costa County, which is where these winds originate."Mount Diablo is an actual mountain peak ...
An anemometer is commonly used to measure wind speed. Global distribution of wind speed at 10m above ground averaged over the years 1981–2010 from the CHELSA-BIOCLIM+ data set [1] In meteorology, wind speed, or wind flow speed, is a fundamental atmospheric quantity caused by air moving from high to low pressure, usually due to changes in ...
The maximum sustained wind associated with a tropical cyclone is a common indicator of the intensity of the storm. Within a mature tropical cyclone, it is found within the eyewall at a certain distance from the center, known as the radius of maximum wind , or RMW.
"Diablo wind" is the local name for hot, dry winds from the northeast that sometimes hit the San Francisco Bay area and central coastal of California, especially in the spring and fall.
