Could a Hurricane Ever Strike Southern California? (October 17, 2012)

Wednesday, October 17, 2012

There's an old adage (with several variations) that California has four seasons: earthquake, fire, flood and drought. While Californians happily cede the title of Hurricane Capital of America to U.S.

GRACE – Uncovering the 2010-11 decline in global mean sea level and its relation to ENSO (October, 2012)

Monday, October 8, 2012

Satellite altimetry observes the height of the ocean surface from space. Globally, the observations are used to determine how much the global sea level is rising due to thermal expansion related to warming and adding water from the melting ice sheets.

Aquarius reveals salinity structure of tropical instability waves

Sunday, July 1, 2012

Tropical Instability Waves (TIWs) are westward-traveling waves associated with shear instabilities of the equatorial current system, and are observed at the edges of the equatorial cold tongues in the Pacific and Atlantic Oceans. TIWs have average wavelengths of 1000-2000 kilometers, periods of 20-40 days, and phase speeds of 0.3-0.5 m/s.

Sea surface temperature anomalies (SSTA) in the Eastern Pacific, specifically off the Peruvian coast, have shown a recent warming.

Warming off the Peruvian coast: Potential Consequences and Implications (May, 2012)

Monday, May 21, 2012

Sea surface temperature anomalies (SSTA) in the Eastern Pacific, specifically off the Peruvian coast, have shown a recent warming. SSTA is defined as the difference between the actual temperature and normal conditions for that time of year.

Coastal Upwelling and Harmful Algal Blooms in Southern California (September-October 2011)
