Environmental Science Assuming that the night will remain clear, calm, and unsaturated, the predicted minimum temperature is 32oF. Suddenly the wind speed increases and remains gusty throughout the night. The minimum temperature will most likely be: Much lower than predicted due to radiational cooling Higher than predicted due to mixing About the same as predicted but will occur earlier in the night Higher than predicted due to the release of latent heat Much lower than predicted due to radiational cooling Higher than predicted due to mixing About the same as predicted but will occur earlier in the night Higher than predicted due to the release of latent heat ANSWER DOWNLOAD EXAMIANS APP
