| Abstract | Este trabalho investiga a variabilidade sazonal das ocorrências de ondas de frio e calor no Rio Grande do Sul e suas relações com os eventos El Niño e La Niña. Foram utilizados dados de 13 estações de superfície bem distribuídas pelo Estado, no período de 39 anos, compreendido entre 1967 e 2005. As relações entre ondas e ENOS foram obtidas a partir da análise de tabelas de contingência 2 x 2 para os meses centrais de cada estação do ano. A significância estatística foi avaliada através do teste exato de Fischer. Observou-se que a variabilidade sazonal das ondas de frio é diferente da variabilidade das ondas de calor. Ocorrem mais ondas de frio nos meses com as temperaturas mínimas mais baixas, e as ondas de calor têm comportamento mais heterogêneo. Na maioria das localidades, é em julho que as relações entre a ocorrência de ondas de calor e os eventos El Niño são mais significativas. Para La Niña e ondas de Frio, o mês com relações mais significativas foi abril. Em ambos os casos, nota-se que há defasagem entre a ocorrência dos eventos El Niño/La Niña e o seu impacto no surgimento de ondas de calor/frio. ABSTRACT: This work investigates the seasonal variability occurrence of cold and warm waves in the Brazilian State of Rio Grande do Sul and its relationships with El Niño and La Niña events. 39 years (1967-2005) temperature data series from 13 uniformly distributed meteorological stations over the State were used. The relationships between waves and ENOS were obtained from 2x2 contingence table analysis for the central months of each season. The statistical significance was evaluated using the Fisher exact test. It was observed that the seasonal variability of cold waves is different than the warm wave variability. There are more cold waves during the months with lowest minimum temperatures, and the warm waves have a more heterogeneous behavior. In most localities, the relationships between the occurrence of the warm waves and El Niño events are more significant in July. For La Niña and cold waves, the month with more significant relationships is April. In both cases, there are lags between the El Niño/La Niña occurrence and their impact in the setting of warm/cold waves. |
