    California Drought-Weather Discussion

    Utrex
    By Utrex,

    Let's discuss about the persisting drought/ridge of California.

    Also... Weather for California in general.

     

    I posted this on westernusawx regarding the ridge's behavior. All it takes is for one of these factors to switch neutral at least.

     

    "The new discovery I just made is that the PDO has been at its lowest since 1977... The beginning of the "warm PDO episodes". I also read about the AMO and its effects to the west coast. If the AMO strives at a positive, it brings drier weather from WA to Socal. If negative, the contrary.

     

     

    No, I doubt this winter will top off a thrusting storm or two. The PDO + AMO, the top dry factors I see are aligned... And their negative/positive levels are quite deep. With the -PDO and +AMO aligned, the ridge will constantly repair itself.

     

     

    If a PDO is negative, a pool of higher height anomalies forms in the North Pacific. By combining the +AMO, that pool of high height anomalies has shifted to the GoA. That's why that ridge won't leave."

     

     

    In addition to these decadal oscillations, QBO is in the westerly phase at the moment. Very soon, it will approach the easterly phase.

     

     

    As we know, the developing +ENSO will *finally* replenish the west.

    Winter has been off to a slow start in Plains. Is there any relief in site for snow lovers? Maybe some more exciting weather as we roll into mid and late Jan.

    Jan came in plowing Chicago with 2 10+ winter storms and a polar vortex that brought record breaking cold to Upper Midwest/Lakes. How the rest of this month shaping up to be?
