Аннотация: The present study aims at estimating seasonal changes of temperature in idealised lakes (lagoons) of the Iberian Peninsular and of the evaporation from the lake surface. The sensitivity of the annual temperature cycle and of the evaporation to climatological changes is examined. To this end, two one-dimensional fresh-water lake models are applied. A series of numerical experiments is performed for lakes that differ in terms of their mean depth. The models are forced with the meteorological data from the ECMWF ERA-40 reanalysis. Results from simulations are compared with observational data. A comparison shows that both models are able to simulate the annual cycle of temperature in lakes of varying depth and to predict the evaporation rates with a fair degree of realism. Analysis of the evaporation rates over an idealised grid box of a general circulation model that is partially covered by lakes suggests that the effect of sub-grid scale lakes should be taken into account.
