Chuvas intensas em Belém nos últimos cinco anos.
Rainfall characteristics are important to specialists in various fields including agronomists and hydrologists, since rainfall is the major factor controlling agricultural productivity and the hydrologic cycle of a region. However, heavy rainfall is ineffective for agriculture and it causes soil erosion. This paper discusses rainfall characteristics dealing with the largest daily and monthly totals occurred in Belém, during the last five years (1997-2001), comparing to a thirty years period (1967- 1930). In order to analyze these rainfall characteristics, rainfall seasonally and the largest rainfall totals for each month and day in the year were studied. The concept of effective rainfall and the results of water balance calculation were also applied. The mean results indicated that the largest daily rainfall totals occurred during the most wet season and that during the last five years, the largest daily and monthly rainfall totals do not exceed the thirty- year period.
