Data provided by the Tropical Rainfall Measuring Mission (TRMM) satellite has helped experts to analyze the unusual flash floods that affected territories from Oklahoma to Tennessee during the first two weeks of August 2013 causing at least two deaths and damages in hundreds of homes and other structures.
In the context of the heavy rains and floods that affected the UK lately, the need for methods how to more accurately predict heavy rainfall over land surface has become evident. Existing computer models used in the UK cannot show exactly where the rain will accumulate and cause problems.
Tornadoes are expected to accompany severe storms in the springtime in the U.S., but this time of year they also usually happen. When a line of severe thunderstorms associated with a cold front swept through the U.S. southeast on Nov. 16, TRMM collected rainfall data on the dangerous storms from space.
Heavy rainfall recorded in December and January (Figure 1) across Southern Africa has caused water-logging and localised crop losses in parts of the sub-region, particularly in Lesotho and across the Zambezi basin. The torrential rains have resulted in elevated river levels, with many regions remaining on alert due to increased possibility of further flooding in downstream areas.
UN-SPIDER was invited by the Guatemalan Council of Science and Technology to participate in CONVERCIENCIA 2009, which forms part of a strategy to promote the development of science, technology and innovation within Guatemala. On an annual basis, Guatemalan scientists working abroad are invited to conduct outreach activities in the country, network with local scientists and practitioners, deliver presentation to the general public and provide advice to the National Secretariat for Science and Technology.
Image shows anomalies in rainfall between July 14 and July 20, 2009. Most of India and Bangladesh are brown, showing that less rain fell than average during the week.

Floods swept across southern China and northern Vietnam in the wake of several days of extreme rain in early July 2009. Although southern China and Vietnam are prone to flooding during the annual summer rainy season, the first week of July 2009 brought unusually heavy rain. The rains caused widespread flooding and landslides that left 75 people dead and 938,000 homeless in China as of July 5, reported China’s Xinhua news. In Vietnam, at least 22 people died, said the AFP news service. More rain was forecast in both countries.
