Impacts of Sea Surface Temperature Warming Pattern Biases on Tropical Cyclone Activity and Hazard

Abstract Most climate models simulate greater warming in the equatorial eastern Pacific than in the west under historical forcing, resulting in a reduced zonal sea surface temperature (SST) gradient and a weakened Walker circulation. This contrasts with observed trends and highli...

Different Last Millennium El Niño Southern Oscillation Sea Surface Temperature Patterns Drive Disparate North Atlantic Tropical Cyclone Characteristics

Abstract Understanding the relationship between the El Niño‐Southern Oscillation (ENSO) phenomenon and North Atlantic tropical cyclone (TC) activity is critical for both seasonal predictions and future projections of TCs. Unfortunately, the satellite observational era (1970‐pres...

Drought dynamics explain once in a century yellow fever virus outbreak in Brazil with implications for climate change

While excess rainfall is associated with mosquito-borne disease because it supports mosquito breeding, drought may also counterintuitively increase disease transmission by altering mosquito and host behavior. This phenomenon is important to understand because climate change is pr...
