Flooding in San Francisco
During the winter of 1997-98, wind-driven waves and abnormally high sea levels significantly contributed to hundreds of millions of dollars in flood and storm damage in the San Francisco Bay region. Recent analyses by U.S. Geological Survey (USGS) scientists of nearly 100 years of sea-level records collected near the Golden Gate Bridge found that these abnormally high sea levels were the direct result of that year's El Niño atmospheric phenomenon.
Prediction of El Nino• Satellites
– provide data on tropical rainfall, wind, and ocean temperature patterns, as well as changes in conditions for hurricane formation.
• Ocean buoys – help to monitor sea-surface and upper ocean
temperatures.
• Radiosondes – balloon-borne instrument platforms with radio
transmitting capabilities, help to monitor global weather and climate patterns
• Super computers – gather all of the weather data around the world and
put it into useful formats used by scientists.– Run models for future change
