Title	Floods in Southeast Texas
Description	Strong southerly winds pumped moist air up from the Gulf of Mexico and across southeastern Texas over the Memorial Day weekend at the end of May 2006. The abundant moisture triggered and sustained thunderstorms over the coastal areas of Texas between May 28 and May 31, 2006. Up to 16 inches of rain were reported in just 24 hours in Chambers County, Texas, east of Galveston Bay, and nearly 12 inches of rain fell in Harris County just outside of Houston. Patches of heavy rain in Southern Texas are clear in this image of satellite-based rainfall totals for May 28-31, 2006. The highest totals (shown in red) occur just inland from the coast near Matagorda Bay along the central part of the Texas Gulf coast where rainfall totals exceed 10 inches (darkest red area). Another area of heavy rain is visible near the border with Louisiana just north of Beaumont, Texas, where amounts are on the order of 7 inches (lighter red area). The totals reported near Galveston Bay and Houston may have been too small in scale (occurred in a very localized area) or occurred over too a brief period to be captured by the satellite, as the image shows relatively low totals in those areas. The image was created from a near-real time, Multi-satellite Precipitation Analysis (MPA) at the NASA Goddard Space Flight Center. The MPA is based on data from the Tropical Rainfall Measuring Mission satellite (known as TRMM, [ http://trmm.gsfc.nasa.gov/ ]) which was placed into service in November 1997. From its low-Earth orbit, TRMM has been measuring rainfall over the global Tropics using a combination of passive microwave and active radar sensors. TRMM is a joint mission between NASA and the Japanese space agency, JAXA. Image produced by Hal Pierce (SSAI/NASA GSFC) and caption by Steve Lang (SSAI/NASA GSFC).

Title	Drought in the Southern United States
Description	Rainfall across the United States in the winter of 2005-06 has shown the classic pattern of a La Niña event. La Niña is a climate anomaly (departure from average conditions) that consists of cooler-than-average sea surface temperatures (SSTs) across the central and eastern Pacific and warmer-than-average SSTs over the western Pacific. Changes in the atmospheric circulation occur during La Niña events, as well. These combined ocean-atmosphere changes are likely responsible for the drought in the Southwest, the South, the central Plains, and Florida that has led to several devastating wildfires this season. This image shows where daily rainfall was above and below average in the United States between October 2005 and January 2006 compared to the eight-year average for that time frame. Places where rainfall was above average are in blue and green, while places rainfall was below average are in orange and red. The data are from the Tropical-Rainfall-Measuring-Mission-based, near-real-time, Multi-satellite Precipitation Analysis at the NASA Goddard Space Flight Center. The Pacific Northwest (green and blue areas), especially along the coast and over the coastal ranges of Northern California, Oregon, and Washington (blue areas) received more precipitation than usual. Almost the entire rest of the country, barring New England, had below-normal rainfall. The most intense rainfall deficits (orange and red areas) include the area stretching from Texas up through the central Plains and Upper Midwest, as well as the Gulf Coast, most of Florida, and along the southern Atlantic coast. In the Southwest, the rainfall deficit added to the stress of several years of below-average rainfall. Most of Arizona, New Mexico, West Texas, and central Oklahoma have received less than 25 percent of their normal rainfall for the period. The current La Niña is expected to persist for the next several months. The Tropical Rainfall Measuring Mission (TRMM) satellite was launched in November 1997. It measures rainfall over the global tropics using both passive and active sensors, including the first precipitation radar in space. TRMM is a joint mission between NASA and the Japanese space agency, JAXA. Image produced by Hal Pierce (SSAI/NASA GSFC) and caption by Steve Lang (SSAI/NASA GSFC).

Severe Thunderstorms over the Southeastern United States

Title	Severe Thunderstorms over the Southeastern United States
Description	Up to ten inches of rain fell over parts of Houston, Texas, between October 10 and October 17, 2006. The rain fell as a line of strong storms, fueled by moisture being pulled up from the Gulf of Mexico, swept across the southeastern United States. Several tornados and deadly flooding were reported across the region. Four people died as a result of the flooding around Houston, said news reports. The top image shows rainfall totals over the southeastern United States for October 10 through October 17, 2006. The rainfall totals come from the near-real-time, Multi-satellite Precipitation Analysis, which is partially based on rainfall measurements made by the Tropical Rainfall Measuring Mission satellite (TRMM [ http://trmm.gsfc.nasa.gov/ ]). The highest totals, shown in red, are around 12 inches (300 millimeters) and occur over north-central Louisiana. Ten-inch (250-millimeter) amounts (lighter red) are visible north of Galveston Bay, and most of eastern Texas and western Louisiana received at least 5 inches (130 millimeters) of rain (green areas). The lower image provides a snapshot of the line of storms at 11:17 p.m. Central Daylight Time on October 16 (4:17 UTC on October 17), as the storm system was passing through central Louisiana. Taken by the instruments on the TRMM satellite, the image shows rain intensity associated with the advancing line of storms. The rains are stretched out in a long, broken line of storms extending from the northwestern Gulf of Mexico through central Louisiana and into southwestern Mississippi. The line of intense rain (dark reds) is relatively thin across Louisiana. A broader area of weaker rain (wide blue and green area) extends farther north. Rain rates in the center swath are from the TRMM Precipitation Radar, a unique space-borne precipitation radar, while rain rates in the outer swath are from the TRMM Microwave Imager. The rain rates are overlaid on infrared data from the TRMM Visible Infrared Scanner. TRMM was placed into service in November of 1997. From its low-earth orbit, TRMM has been measuring rainfall over the global tropics using a combination of passive microwave and active radar sensors.

Title	Thunderstorms in Texas
Description	Torrential rainfall in southeast Texas and southwestern Louisiana on June 19, 2006, caused extensive flooding. The rains caused waist-high flooding in the Houston area, according to news reports. A surface and upper-level trough (a region of low atmospheric pressure) along the Texas and Louisiana coast generated heavy showers and thunderstorms. The image above shows rainfall totals based in part on measurements taken by the Tropical Rainfall Measuring Mission (TRMM) satellite from June 13-19, 2006. The highest amounts shown on the image are more than 228 millimeters (about 9 inches). The heaviest rains occurred over north-central Texas and on the Gulf Coast along the Texas-Louisiana state line. The animations provided above show the day-by-day accumulation of rain. TRMM was launched in November 1997. The rainfall analysis above is from TRMM-calibrated precipitation estimates called Multi-satellite Precipitation Analysis (MPA). The MPA estimates were developed by the precipitation research team at NASA Goddard Space Flight Center. Images and caption produced by Hal Pierce (SSAI/NASA GSFC).
