Marine Heatwaves: Causes & Impacts

Causes

• Regional Climatic Patterns: These patterns encompass local conditions, including ocean advection, air-sea fluxes impacting warming between the ocean surface and the atmosphere, thermocline stability, and both regional and global wind stress.
• Teleconnection Processes: This process links geographically distant areas through weather and climate patterns.
• Significant teleconnection processes involve atmospheric blocking or subsidence, the positioning of the jet stream, oceanic Kelvin waves, elevated surface air temperature, and seasonal climate oscillations like El Niño Southern Oscillation (ENSO) that contribute to marine heatwaves.
• Additionally, anthropogenic ocean warming due to climate change, ocean currents' ability to accumulate warm water leading to MHWs, and ....
