Número de postos pluviométricos necessários para a estimativa da precipitação mensal no estado do Espírito Santo, Brasil

Abstract: RESUMOOs objetivos propostos nesse trabalho foram, determinar a distribuição espacial da precipitação pluvial média mensal no Estado, utilizando a altitude dos postos pluviométricos como co-variável e, determinar o número de postos necessários para mapear a precipitação, considerando a dependência espacial. Os dados para realização desse estudo abrangem séries variando de 33 a 72 anos, totalizando 55 postos pluviométricos. Os dados foram submetidos a uma análise descritiva e geoestatística. A co-krigagem usand… Show more

“…Variations in the spatial-temporal distribution of rainfall, associated with low annual rainfall regimes in the largest portion of the state, have a direct impact on rainfed agriculture. Knowledge of this agrometeorological variable could guide decision making for agricultural management, as in the study of zoning, crop forecasting and climatological characterization, since the high variation of pluviometers can lead to gross planning errors, causing serious losses due to high water deficits that may occur and are not predicted in studies (Silva & Lima 2011).…”

“…An example of this relationship are the adversities of long periods of drought and high temperatures, influenced by climatic and oceanic phenomena such as El Niño (Hastenrath 2012). In the midst of these events, many research has been conducted over the years in several Brazilian states, with the aim of monitoring and evaluating environmental variables more precisely and analyzing climatic conditions, as well as their spatial and/or temporal variations, as described by Sartori et al (2010), Santos et al (2011) and Silva & Lima (2011) for the states of São Paulo, Goiás and Espírito Santo, respectively.…”

“…Esta distribuição espacial da precipitação está de acordo com Silva & Lima (2011), que verificaram que os menores índices de precipitação ocorrem na região norte, oeste e litoral sul do Estado do Espírito Santo; e com os maiores índices, em parte, no litoral sul e região serrana sul.…”
