| Description |
This image shows differences in atmospheric water vapor relative to a normal (average) year in the Earth's upper troposphere about 10 kilometers (6 miles) above the surface. The measurements were taken by the Microwave Limb Sounder (MLS) instrument aboard NASA's Upper Atmosphere Research Satellite (UARS). These data, collected in late December 1997, show higher than normal levels of water vapor (red) over the central and eastern Pacific which indicate the presence of an El Nino condition. At the same time, the western Pacific (blue) is much drier than normal. The unusually moist air above the central and eastern Pacific is a consequence of the much warmer than normal ocean waters which occur during El Nino. Warmer water evaporates at a higher rate and the resulting warm moist air rises and forms tall cloud towers. In the tropics, the warm water and the resulting tall cloud towers typically produce large amounts of rain. These data show significant increases in the amount of atmospheric moisture off the coast of Peru and Ecuador since measurements were made in November 1997. The maximum water temperature in the eastern tropical Pacific, as measured by the National Oceanic and Atmospheric Administration (NOAA), is still higher than normal and these high ocean temperatures are likely responsible for an increase in evaporation and the subsequent rise in humidity. |

Sea Surface Temperature Anom
…
| Title |
Sea Surface Temperature Anomaly, 2005 (WMS) |
| Abstract |
The temperature of the surface of the world's oceans provides a clear indication of the state of the Earth's climate and weather. The sea surface temperature anomaly, or difference from the mean, can show climate indicators such as the El Nino oscillation, which manifests as a warmer-than-normal sea surface temperature in the Pacific Ocean west of Ecuador and Peru. This sequence shows a slight La Nina effect, or cooler-than-normal sea surface temperature in the eastern Pacific. |

Flooding in Northern Peru
| Title |
Flooding in Northern Peru |
| Description |
Northern Peru's rainy season was coming to an end when the Moderate Resolution Imaging Spectroradiometer (MODIS [ http://modis.gsfc.nasa.gov ]) on NASA's Aqua [ http://aqua.nasa.gov/ ] satellite captured the top image of the region surrounding the Bay of Sechura. The barren land, pink-tinted tan in January, the middle of the rainy season, was covered with patches of blue water on April 30, 2006. The rainfall also brought a faint brush of green to the desert, with brighter patches of green in irrigated areas along the top and bottom of the image. Clouds are pale blue and white. Though Peru escaped major flood-related damage, both Ecuador and Colombia, immediately north of the region shown here, suffered as floods damaged crops, isolated houses, and triggered landslides, reported the Dartmouth Flood Observatory [ http://www.dartmouth.edu/%7efloods/Archives/2006sum.htm ].
