Hurricane Oli seen by altimetry
Category: News of the Jason-2 mission, Ocean and climate news
Islands of French Polynesia in Pacific Ocean have been hit by the hurricane Oli since the beginning of February. Oli is classified in Category 4 (winds > 213 km/h) on February 4 off Bora-Bora islands. Rainfall and high seas have damaged lands. During the current El Niño episode, the Eastern Pacific hurricane season may be more active.
A parameter nammed Tropical Cyclonic Heat Potential (TCHP) integrates the sea level anomalies with the in-situ sea surface temperature and the mixed layer depth. Computed around the area, the TCHP shows important values (more than 140 kJ/cm²) at the end of January.
