Resumo
The objective of this study was to establish sequences of rainy days as a risk factor
for agriculture in the southeast region of the states of Goias, Brazil. Rain gauge data from 36 rain
stations were used. The sequences of rainy days were calculated by a computational routine for
December, January, February and March. The probability of sequences was estimated by using the
TNBD (Truncated Negative Binomial Distribution) and was verified by Chi-square distribution.
The result were regionalized obtaining figures related to sequences of rainy days for the months
studied. Results showed that the risk of rain sequences varies locally. Higher probability for
occurrence of two rainy days occurred in the center, southwest and south of the analyzed region,
and 3 days in the central region and surroundings. There was low probability for occurrence of 4 or
more rainy days.
