On that day, air quality levels on the Nipomo Mesa moved into unhealthy levels at 145 PM10 as compared to 30 in San Luis Obispo or 18 in Atascadero. David Middlecamp/dmiddlecamp@thetribunenews.com
The vertical extent of the dust or sand that is raised is largely determined by the stability of the atmosphere above the ground as well as by the weight of the particulates. In some cases, dust and sand may be confined to a relatively-shallow layer by a low-lying temperature inversion. In other instances, dust (but not sand) may be lifted as ...
The stormy pattern will continue this weekend, with milder air expected to move in and cause snow levels to rise. The combination of rain and snowmelt will further increase the risk of flooding at ...
A precipitation outlook from the Weather Prediction Center shows heavy rain and snow are expected across the Northwest and south-central U.S. between Dec. 26, 2024 and Dec. 28, 2024
The high winds were also caused by a series of events. Over the Great Basin, which is located in Nevada and Idaho, the air was very cold and heavy (high pressure). A very strong low pressure system was approaching the northwest coast of California. A mercury reading of 0.10 inHg (3.4 hPa)of pressure gradient force (difference of pressure ...
High winds and blowing dust were reported throughout central California on November 29, 1991, both in the San Joaquin Valley and the Salinas Valley.A weather station at Naval Air Station Lemoore, the closest one to the crash site which tracked wind and visibility statistics, measured wind gusts up to 21.6 metres per second (48 mph; 78 km/h) and visibility as low as 0.5 kilometers (0.31 mi).
In the West, heavy rain and snow chances increase on Tuesday as "another atmospheric river event arrives" across parts of central California, the National Weather Service said in a Sunday forecast ...
Sand blowing off a crest in the Kelso Dunes of the Mojave Desert, California. Aeolian landforms are formed when wind moves sediment (see aeolian processes). Sediment particles move when they are lifted by upwards Bernoulli forces that exceed their downwards weight or when they are dragged from their initial position. Depending on the balance of ...
