Marine heatwaves are periods of persistent anomalously warm ocean temperatures, which can have significant impacts on marine life as well as coastal communities and economies. Scientists at PSL are working to characterize marine heatwaves, understand how they form and dissipate, and predict them in advance. The page provides current ocean maps, forecasts of heatwaves, interactive tools for users to explore ocean heatwaves themselves, links to research results and to webpages at other institutions.
Atmospheric Rivers (AR) are relatively narrow regions in the atmosphere that are responsible for most of the horizontal transport of water vapor outside of the tropics. PSL studies them to better understand their potential impacts.
Wind power is a variable power source, dependent on weather conditions. Having advance knowledge of when wind power will ramp up or down through accurate weather forecasts can lead to significant improvements in the efficiency of operation of fossil fuel plants, as well as the entire electrical grid system, resulting in lower costs as well as lower CO2 emissions. PSL deploys instruments and analyzes observations of the boundary layer and lower troposphere, especially using radar wind profilers and microwave radiometers among other instruments. These instruments provide data sets to be assimilated into numerical weather prediction models and that can be used to improve the physical parameterization schemes in those models..
