Não é, mas pode dar origem a miragens. :rolleyes:
Hoje, estava mesmo a referir-me à miragem do ECM. Embora, quando isto levantar passa logo do 8 para 80. Esperamos que seja um Verão bem mais suave do que no ano passado. :D

Temos tido episódios quentes em todos os meses desde Janeiro logo nada me espanta daqui para a frente. Desde que não passe dos 45°c está bom :D

By closely examining details of the atmospheric patterns that developed near the region in the months before the blobs began, they found that nine of the 13 warm blob events occurred during the positive phase of the North Atlantic Oscillation (NAO), a weather pattern over the North Atlantic ocean consisting of fluctuations in pressure between an area near Iceland and one near the Azore Islands off the coast of Portugal.
Physically, these planetary wave trains are triggered by increased rainfall and latent heat release over the Mediterranean Sea and are accompanied by decreased rainfall over the North Atlantic. This scenario can transport wave energy to the northeast Pacific Ocean, guided by the westerly jet stream, and induce the anomalous pressure ridge there.

Ten of the 13 warm blob events, about 77%, corresponded with higher-than-normal rainfall over the Mediterranean region. Variations in that region could play an important role in sustaining the Rossby wave train and hence the anomalous ridge over the northeast Pacific.
