  1. The close CoCoRahs to Copperopolis is Angels Camp reporting 4.67" and raining. Here is the link https://maps.cocorahs.org
  2. Seems the AR is not just a Pacific event as discussed in this article. AR-blessing and a curse https://weather.com/science/weather-explainers/news/atmospheric-river-explained Moving flooding rain to snowpack storage is one of the main purposes of aquariusradar. The politicians in charge of finding solutions to California water shortages breathe a sigh of relief as they see the current AR eliminate immediate need for research on drought mitigation. The voter concerns are temporarily quelled. It is but one AR. As in the past, the drought problem goes away until the next dry emergency returns.
  3. This LA Times article describes the Atmospheric River Atmospheric River https://www.yahoo.com/news/series-storms-atmospheric-river-barreling-181229757.html I have copied the article illustration and annotated the Cumulo-Nimbus clouds CN A and CN B for both the coastal mountain case and the Sierra Mountain case where aquariusradar can be used to alleviate flooding if the Atmospheric River does indeed turn out to be a class 4-5. For coastal flooding of a river drainage basin or from burn scar flooding, the microwave energy is focused on CN A which slows the development of CN A and allows CN B to take up the added moisture. More rain falls from CN B on the summit or valley side of the mountain(s). Less falls from CN A on the burn scar or flooded coastal side. In the Sierra case, again CN A is targeted and less rain falls on the burn scar western slope. CN B takes up the added moisture and more moisture falls as snow above the snow line and on the mountain crest. Because CN cells are always in competition for moisture, the inhibited CN cell yields moisture to the neighboring uphill or downwind CN cell. Overall rainfall is unchanged. Water is transported to storage. Snow in the Sierra case. Maybe a reservoir in the coastal case or maybe snow on Shasta or Lassen if in far Northern California.
  4. I developed a primitive short term predictive tool that I call the Upper Dryness Index for the southern half of the Pacific high. This plot is the results for the first month of the water year. It's a rough estimate of the area, in square kilometers, with an indicated temperature greater than -5 degrees centigrade of the upper IR satellite view of the tropical Pacific. The index starts the year at a high ? level (dry) and trends down through the end of the first month and into October. The index is low ? (wet) at the moment and is concurrent with the approach of more powerful Aluetian cyclones into the northern half of the Pacific high and atmospheric river events. Does it mean anything? Time will tell.
  5. Time to clean out the downspouts to the water barrels. Gonna save enough for the cacti to last all year.
  6. The approaching trough has a monster circulation and moisture to work with too. Could really rain in SoCal!
  7. The recent trough that ran down the coast didn't have a great deal of wet air to work with so SoCal received little rain. The flow of ITCZ moisture on Saturday the 16th that ran over Hawaii and pressed towards the central coast looked encouraging. But the south moving trough and associated front could not knife through the high pressure ridge; the trough simply pushed the edge of the high south and detoured the moisture flow to the Baja. Again the high pressure is the boogeyman of drought. The flow of moisture is feeding across northern Mexico into Texas and the plains states. That will help with rain when the low sweeps across that area. The next Aleutian cyclone approaching is now large with a good moisture on the south side. Forecast to reach California and make some rain.
  8. CoCoRaHS reporters are also good sources for a monthly total. You can identify a reliable reporter when every day of the month is consistently reported each year for several years. Some can be spotty or misleading. Some don't have the gauge set up properly.
  9. I am trying to create a very simple short term predictive scheme that would loosely follow the NWS predicts for middle and southern California. Right now it consists of guesstamitts of the area in square kilometers of extreme dryness of the southern half of the Pacific high. The daily rough estimate in square kilometers is taken from the upper IR satellite that shows yellow greater than -5 centigrade temperature. This example for the first of the year does show a trend down. But it has no meaning unless this and future data show some correlation to California weather.
  10. LA Times article tells us again what we already know. dry winter predicted https://www.yahoo.com/news/la-ni-back-does-mean-120038454.html Hope US NWS is wrong.
  11. The upcoming period 21-27 Oct is predicted to be a significant rain event for the central and northern California coast and mountains. The aquariusradar action to help store more rainfall as snowpack is described on my web page Snowpack Enhancement http://aquariusradar.com/snowpack.html During atmospheric river events, the details about a potential testing method is described on this page California test http://aquariusradar.com/californiatestproposal.html
  12. Pamela turned into the continent way too early. Not a drop for the Southwest. Gonna help soak Texas and the Plaines states. Pacific storms for 2021 are turning out to sea or turning inland. We don't get help this year-so far. Maybe a late storm will run up the Baja for SoCal and the Southwest.
  13. A water vapor molecule is 282 picometrs diameter. The mass of a water vapor molecule is 18 gram/mole. A nitrogen molecule is 300 picometers in size and mass 28 g/mole. Air that contains high concentrations of water vapor are deflected by air masses without water vapor; the dry air being more massive per volume than wet air. The giant blocking high off the California coast is very dry air. Subtropical jet streams that guide moist air northward and eastward from the ITCZ are deflected by the blocking high; routed up and over on the north side of the high and to a lesser degree down and under on the south side of the high. If the blocking high could be made more wet, the eastward moving wet air would not be deflected as far away (north or south) from California. I have previously discussed how aquariusradar could be used to “wet” up the hulking high. That idea might be to difficult for politicians to understand as politicians don’t bother with understanding how science can help. But some are aware of geoengineering-a buzzword easy on the tongue- and how it might be used to resolve the drought problem. Unfortunately, politicians make these decisions-not scientists. A recent natural phenomena of the western Atlantic and Caribbean Sea points to a possible solution. An explosion of Sargassum seaweed has resulted as large volumes of Saharan dust are deposited over the waters of this area. The dust, rich is minerals, has encouraged the growth of the seaweed ( beneficial surface Sargassum fluitans and Sargassum natans) not to be confused with the bottom dwelling nuisance Sargassum horneri of the near coastal waters of the Pacific. By “farming" huge areas of floating rafts of Sargassum in the Pacific under the dome of the hulking Pacific high, the natural inversion created by the cooler waters below the warmer air above in the area of the dome would be overcome by the warmer surface temperatures created by the floating mats of seaweed.The weed is dark with a low albedo allowing most of the incident sunshine to be absorbed at the immediate surface. During daytime heating, evaporated water leaves the surface warmer than the surrounding air. Then low pressure systems that approach the “farm” of Sargassum can then take up moisture because of the more buoyant air available. A hotspot of instability could be maintained by feeding necessary minerals to the seaweed for growth in a defined area - the farm- from airplanes. Patches of weed that drift away are harvested when the drift of the escaping weed would wind up on someones beach as a environmental or undesirable mess- tourist areas maybe. The harvested weed could be used as livestock feed. But most of the weed would be held in place by the gyre, just as in the Atlantic sea of Sargasso. Hotspots are common in the warm waters of the worlds oceans. The hot spot CN cell can be initiated by solar heating and continued by drawing in the low level water vapor trapped under the surrounding inversion. In the area of concern, the CN cells generated stream moisture away to the northeast. The Pacific surface where moisture must rise, be transported by westerlies, and be valuable for rain in California is generally in cool waters and hot spots are infrequent. The Sargassum farms create hotspots that route moisture to the California coast. The hotspot location can be maintained such that the moisture can be aimed to the desired coastal or mountainous region. Rainfall would be dependent on orographic lifting or coinciding and colliding with cyclonic/frontal systems. One obvious place for the farm would be the huge eastern Pacific garbage gyre- the collection’s of plastic garbage that sets under the dome of the anticyclonic rotation between California and Hawaii. The albedo of the plastic garbage gyre is high- the plastics reflect much of the sunlight and don’t allow much near surface water heating. This is cooler surface water. It’s situated in a location that would send hot spot moisture, created by the sargassum farm, directly into the heart of the high pressure dome. High altitude moisture would be forced eastward to the California coast. The floating trash would soon be covered by dark sargassum weed and the weed patch would be held in place, much like the trash, by the gyre.
