Abstract
Weather research and forecast (WRF) model simulations are used to investigate how the distribution of precipitation is related to the distribution of sea surface temperatures (SSTs) during the life cycle of the Australian east coast low of 7–9 June 2007. The focus is placed on investigating changes caused by the introduction of complex ocean eddy and filament structures present in the Bluelink ReANalysis (BRAN) SST data set. In the simulations, enhancement of rainfall is found over and downwind of warmer SSTs and suppression of rainfall over and downwind of cooler SSTs. Specifically, a large warm eddy present during this case is associated with an enhancement of rainfall along its downwind (..
