The effect of sea surface temperature and deforestation on the mid‐summer drought over Mexico and Central America
Abstract We analyse the effects of deforestation and the projected differential sea surface temperature (SST) anomalies between the tropical North Atlantic and the eastern North Pacific on the mid‐summer drought (MSD) over southern Mexico and Central America. To address these issues, we performed a...
