   Do extreme polar vortex "dips" only occur over a continent?

   November 8, 2014 by Sandy Loam

   Does anyone know why these recent, prolonged dips of the polar vortex tend to occur only over a large continent, but not really over oceans? Obviously, it has happened over North American a few times in recent years. It also occurred over central and eastern Europe in early 2012. I know nothing about the polar vortex phenomenon, but I have noticed that the pattern seems to be an extremely low-latitude dip in the jet stream which causes the polar vortex to "get stuck" in a particular spot for a while, but I haven't noticed this pattern occurring anywhere in recent history except over continental land masses. Is there something about oceans that prevent the jet stream f…

   Anybody checking the weather in the bay area?

   I was looking at weather.com and the weather doesnt look likes going to be pretty. Noaa calls for snow showers lowering down to around 1000 with lows in the mid 20's around January 11. The next days it says it will be in the mid to upper 20's. I have found weather.com to be very conservative. Weather is calling for a low of 36 in SF. weather.com also says mid 20's throughout central valley. Just a heads up folks.

   Short video. The only day of rain we have had (until now) this winter.

   Video taken Jan 9th 2018 Rain began at noon lasted till dawn. We had a break right before 5pm, took this short quick video. Temps dipped to 8C/46F right before dawn the next day. So I turned on the IR heat lamps from 4pm (9th) till 9am (10th). It's probably overkill, but I must admit, this winter (knocking on wood), has been very benevolent with us. Days in the 70-80's and nights in the 50's. This time last year, I had the coconuts completely covered. I think last years winter rainfall was a record-setting one. So far, I have set up the tarps only to deflect the cool rain from pelting directly onto the coconuts. This weekend they're calling for 80…

   Red Tide Watch

   • 709 views

   For anyone locally, ( Tampa/Sarasota area) or others considering possible beach trips while in the area over the next couple weeks, be advised that a closely monitored Red Tide which has been lurking roughly 40 miles just off the coast is looking more certain to reach the beaches in coming days, esp. with the wind pattern looking to stay moving west to east. According to the latest observations, it has elongated from roughly 50-60 miles in length to 90 miles currently. It is also looking to be one of the largest blooms since 2006. Already, had noticed something "different" about the water quality along the beaches/ shorelines along the mouth of the Manatee River/ Sara…

   Interesting climate data for CA

   Here's an interesting article regarding climatic changes in central and northern California. It's pretty common to colloquially talk about the lack of winter fog among Fresnans but it's interesting to see actual research concerning it. From a cultivation perspective, I think that the lack of heavy winter fog contributes to more sunny winter days which in turn helps marginal plants edge through winter. https://news.berkeley.edu/2019/04/10/falling-levels-of-air-pollution-drove-decline-in-californias-tule-fog/

    Aloha from Maui! Had a pretty decent earthquake here this morning about 6.5...Any damage to speak of around the islands? Only power outages here around the hotel, we are on generator power and the wireless internet still is working along with cell phone service.

    Cheer up the average temperatures start going back up in January. At least here in TX, and in FL, they bottom out around now and start going back in the right direction. CA, probably not yet. In another couple months cold weather will be a distant memory.

    What's Up?  How Cold in Cali?

    January 9, 2007 by happ

    • 1 reply
    • 879 views

    The much touted "Cold Spell" is receiving lots of attention & opinions. At best it should be bad news for frost-prone areas like Oceanside plain/Vista/San Marcos/El Cajon. Metro areas should stay above 40F though NWS predicts 39F in San Francisco Saturday morning. Bay Area will be especially cold in areas away from the water. Wind may be the worst part of the system since the cold dry air massing in western Canada will ride a low pressure into the PacNW/RockyMts forcing/funneling tight millibars. So long as it stays windy the night temps will modify but super dry air will cause damage. It is strongly urged to irrigate heavily before this event. Hope for…

    Evrotas Valley summer average highs (beats Cordoba)

    Following up from a previous topic where we hypothesized than areas further inland and North of Sparta would have higher summer average maxes Well it appears that the National Observatory of Athens has been running a secondary Hydrometeorological station in the depths of the Evrotas Valley around 10 km North of Sparta the past 4 years. Below some pics of the Evrotas station and its position relative to Sparta WMO met station. And below is how Evrotas NOA station looks the past 4 years. Notice the particularly pronounced summer average highs. Especially that July 40.5C average max. Again we are talking about only 4 years of…

    The fire smoke has been so bad this summer that even the moon is orange. Good news is the winds are changing tonight with offshore winds blowing all that smoke away. Hugh cool down also. Sorry, not the best picture but you get the idea.
