Rapidly Intensifying Hurricanes Portend Trouble in a Warming World
Nov. 19, 2020
The 2020 season will go down in history for the dominance of the fast-blooming storms that prowled the Atlantic, raising the question of whether this is the new normal.  Ten storms rapidly intensified this Atlantic season, some to a record degree. (CIMES Director

Large, Delayed Outbreaks of Endemic Diseases Possible Following COVID-19 Controls
Nov. 11, 2020

Measures to reduce the spread of COVID-19 through non-pharmaceutical interventions (NPIs) such as mask wearing and social distancing are a key tool in combatting the impact of the ongoing coronavirus pandemic. These actions also have greatly reduced incidence of many other diseases, including influenza and respiratory syncytial virus (RSV).

Oct. 28, 2020

In a new study published in Nature Communications, the authors used multi-year observations from a very large array of robotic drifting floats in the Southern Ocean to determine key factors governing phytoplankton biomass dynamics over the annual cycle. Their…

Estuarine Forecasts at Daily Weather to Subseasonal Time Scales
Oct. 23, 2020

Estuary and coastal ocean forecasts based on predictions of temperature, salinity, currents, and storm surge have been shown to be able to protect lives and property from storm surge, assist search and rescue operations, and protect public health. These forecasts enable predictions of harmful algal blooms and the dispersion of oil spills. Many…
