Matthew Lunger OCE1001 This is a page on the web that deals with the effects that the El Nino has on the globe. The El Nino effects the temperature and the precipitation amounts that fall on the globe as well as effecting the winds that run in circuit around the earth. During the 1997 El Nino, The precipation average in most of the U.S increased by more than 3 inches, except along the Pacific coast where rainfall dropped conciderably. This drop in rain causes droughts and directly effects human health. These droughts cause water shortages, make it difficult to grow crops, and increase the intensity of forest fires. Also, the increased water temperature in the pacific makes fishing more difficult and causes increased global prices for fish as well as hurt the people whose main diet consists of that fish.

Unformatted text preview: http://www.pmel.noaa.gov/tao/elnino/impacts.html#part4 During El Niño the trade winds weaken and warm water moves back east in a slow wave. This leads to a reduction of the thermocline in the eastern Pacific and an increase of the thermocline in the western pacific. Coastal upwelling along South America is no longer able to tap into the cold, nutrient-rich water from beneath it, thus reducing the supply of chemical nutrients. As a result of this decrease in nutrients, there is a drastic decline in phytoplankton production, which in turn adversely affects all the creatures at higher levels of the marine food chain. This causes many of the fish that support life in the Peruvian area to disappear and thus effect that economy. http://www.csa.com/discoveryguides/archives/elnino.php...
