Here is my weekly weather quiz question for the last time. The city of San Francisco, CA has it’s own “air conditioner” caused by upwelling. What is “upwelling” and how does it keep the area cool? Upwelling in ocean dynamics, the upward motion of sub-surface water toward the surface of the ocean. This is often a source of cold, nutrient-rich water. Strong upwelling occurs along the equator where easterly winds are present. Upwelling also can occur along coastlines, and is important to fisheries and birds in California and Peru. Upwelling off San Francisco keeps replacing the warmer surface water with colder water from the depths and thus breezes blowing from the ocean have a cooling effect on the land. I’ll have a new weekly weather quiz question for you starting Monday. Please remember to post your answer as a comment by clicking on “no comments /comments” in the upper right hand portion of this page under the caption, then add your comment. The first person to post the correct answer will win a week of free personalized weather forecasts tailored to your needs. The answer has to be a comment to win. An email answer will not count. Good luck.

ADVISORIES:

A Blue-Green Algae warning continues for Tenmile Lakes in Coos County, Fern Ridge Reservoir, Lost Creek Lake,  Devils Lake and Willow Creek Reservoir (NE Oregon). Water monitoring has confirmed the presence of blue-green algae that can produce toxins, state public health officials said. The algae levels are likely associated with dangerous cyanotoxin concentrations in the water that can be harmful to humans and animals. Swallowing or inhaling water droplets, as well as skin contact with water, should be avoided according to the authorities.

An upper level low (Shaded “U” shape) will keep us in clouds and rain for a while. A frontal system has moved through the Pacific Northwest, pushed by the upper low, bringing colder wetter weather. Look for a strong frontal system to approach Oregon by Thursday adding more moisture to the mix.
