August 30, 2007 -- Weather Trivia

Everybody's complaining about how hot the weather is. The high temperature in downtown Los Angeles today was 91 degrees at about 3:00 PM. That's really not that bad...

TRIVIA QUESTION:

What was the highest temperature ever recorded for Downtown Los Angeles?


TRIVIA ANSWER:

112.0 °F (44.4 °C) on June 26, 1990

The average high temperature in August is 82 degrees.



In August 1999, the NWS moved the official downtown Los Angeles weather station to the USC campus, 3.78 miles (almost 6 km) to the southwest of its previous location near city center at the Department of Water & Power (DWP).

This move resulted in a significant change in weather records which could influence climatic studies of the city.

A comparative study of daily temperatures and precipitation recorded at USC and DWP, clearly shows that the move resulted in a significant decrease in both temperatures and precipitation.

These comparisons show both diurnal and seasonal differences. For the 1999-2006 record, maximum temperatures averaged 1.5oF higher at DWP, but nearly the same for minimum temperatures (mean values being 0.7oF higher at DWP).

Greatest temperature differences between the two stations occur in late summer and early fall, while the winter records showed the least differences.

Aerial photos show the land use differences between the two sites. The USC site resembles a park, with tall shade trees close to the instrument shelter. The DWP site is located on the roof of a downtown parking structure, with no vegetation nearby. The USC site is also closer to the ocean (and sea breezes).
