The impact of changes in the weather on the surface temperatures of Windermere (UK) and Lough Feeagh (Ireland)

Resumo:

The surface temperatures of Lake Windermere (UK) and Lough Feeagh (Ireland) have been recorded every day since 1960. Here, we examine the factors influencing these measurements and their associated weekly variance. At both sites, there was a progressive increase in the measured temperature but the rate of increase was very much greater in Lake Windermere. The variance of the Lake Windermere temperatures was negatively correlated with the cloud cover but there was no corresponding change in Lough Feeagh. Comparisons with the Lamb system of weather classification showed that the lake temperatures were closely correlated with these synoptic conditions. The highest winter temperatures were recorded during ‘westerly’ conditions and the highest summer temperatures under ‘southerly’ conditions. The most striking difference between the lakes was their response to cold winters and windy summers. Such results demonstrate that, lakes that are physically very similar can still ‘filter’ the climate signal in subtly different ways.
