The “Ridiculously Resilient Ridge,” sometimes shortened to “Triple R” or “RRR,” is the nickname given to a persistent region of atmospheric high pressure that occurred over Southern California. Finally today there is an article about this condition in the Los Angeles Times. The well-known weather forecasters are all in agreement that as long as this condition continues there is a likelihood that the predicted El Niño rains for this part of the nation will not occur. Apparently they cannot predict when the high pressure ridge will dissipate sufficiently to permit consequential rain in the Los Angeles-San Diego region.
Yesterday the temperature was in the high 70s and low 80s in the Los Angeles area. Other than an expectation of 1 to 2 inches of rain on Sunday January 31 there is a forecast of moderately warm dry temperatures for the coming week. The condition will be caused by that RRR.
Local KABC-TV chief meteorologist Dallas Raines, certified by the American Meteorological Society, has been voicing doubts about El Niño for the last month. He does an excellent job of explaining air circulation and high pressure.
As an amateur rain collector since the last El Niño I can report that to date my rain gauge has collected just of 6.5 inches of rain compared to last year’s 8.4 inches of rain. Obviously 1 to 2 inches of rain this weekend won’t change the current trajectory of a very dry year.
Happily the storms in the Sierra Nevada Mountains are significant and that will ease the drought. Meanwhile Southern Californians will continue to lounge by their pools and spend their free time in the parks.
