The degree of severity of each storm event for the city is shown to depend also on the extent of heavy rain areas and therefore on the spatial structure of rainfall intensities.
Forecasters downplayed the threat of Diane after it weakened over Virginia; the Weather Bureau agreed they did not foresee the extent of the rain that would occur, instead calling for just "some local flooding".
Based on the estimated dates, much of the subsequent diversification in the Attaleinae can be attributed to the Andean uplift from late Miocene through the Pliocene [91] [93], and Pleistocene fluctuations in the extent and location of rain forest and seasonally dry climates in South America [94], [95].
Amazônia is one of the most important ecosystems of the planet, containing the largest extent of contiguous tropical rain forest on earth, over 5 million square kilometers.
This might be attributed to the high density of monitoring stations in comparison to the spatial extent of a typical rain event.
The eastern edges of the plateau and, to a lesser extent, the coastal fringes receive much smaller quantities of rain from a northeasterly airstream that arrives in winter and spring.
The extent of the wettest rainforests, which receive more than 100 millimeters of rain per month, shrank by 80%.
Aerial video footage and images captured on Friday by videographer Payton H. Peterson show the extent of the damage in Longmont and Lyons in Boulder County after 12 inches of rain.
On October 1, 2009, the Briga catchment and the surrounding area for a total extent of about 60 km were hit by an intense storm with more than 220 mm of rain in 7 h with peak of 10.6 mm in 5 min measured at the St. Stefano di Briga rain gauge (Maugeri and Motta 2011).
Because of the paucity of rain gauge data in many mountainous regions, however, it is not certain to what extent PRECIS overestimates precipitation.
