WebThe meaning of OVERDAMP is to damp in excess. How to use overdamp in a sentence. Websuch as damped anomaly persistence. Results indicate that the tendency for climate forecasts based on combined out-put from multiple prediction systems to outperform any one system, demonstrated previously for global variables such as temperature and precipitation, is realized for predictions of Arctic sea ice as well.
