Another dry 'inside slider' winter for Los Angeles?

Badly needed rains in Los Angeles continue to be put on hold.

Scientists hoping for overdue "El Nino” west coast winter rains came up empty handed last winter, and so far, this year, a repeat performance seems to be in the making.

For a number of complex scientific reasons, the abnormal warming of the equatorial Pacific - which is the trigger for major changes in high-level jet stream winds which guide winter storms toward North America—appears once again, to be absent.

The normally present California current, which is largely responsible for the Southland's temperate and desirable year-round climate continues to provide its cooling (and drying) influence. At the same time, strong Great Basin surface high pressure associated with upper-level ridging along and off the west coast continues to be well entrenched, and shows no signs of a major breakdown.

Such was the overall weather pattern last winter, with the resultant parade of 'inside slider' type of storms, following its usual routine of bypassing southern California altogether or bringing only scanty showers, followed by drying, gusty Santa Ana-type winds.

Noticeably absent in recent years—the strong, low-latitude direct west-to-east flow of moist sub-tropical air responsible for powerful, drenching storms during the 1980- 2000 or so era seems to be continuing its hiatus.

Long-range forecasts aren't hopeful at the present time. Below normal rainfall continues to be the prognosis across the southwestern U.S. for the coming months, and barring any unforeseen, unexpected developments—will likely play itself out.

Climate change and global warming—the usual suspected culprits in this and related weather anomalies—may or may not be the major players. Long-term atmospheric behavior is far from being fully understood despite the claims of some “experts”

...For now, we'll just have put away the umbrellas and hope...keeping in mind that we are, indeed at the mercy of whatever the whim of this vast 'ocean of air' is that surrounds and encompasses us. ***
