Heavy rain and strong wind

During strong storms, water can splash off the horizontal bottom plate of the anemometer envelope and interrupt the signal passing between the sonic transducers. Despite these features, heavy rain and strong winds can cause water to reach the membranes and also cause temporary water buildup on the acoustic mirror. The hydrophobic nature of the transducer protective membranes and the quick-draining ability of the acoustic mirror should limit wind measurement interruptions to heavy rain and bring wind measurement back online soon after extreme conditions abate.
