An Update on Global Soil Moisture Anomalies

The most remarkable soil moisture regimes are the persistent and historic wet soil moisture regimes across eastern tropical Africa and India. The wet soils in this area are the result of the positive Indian Ocean Dipole which peaked in intensity last October. Warm SSTA across the tropical Indian Ocean may try to sustain this wet pattern despite the collapse of the +IOD.

Epic +AO Could Inspire Strong Severe Weather.

The January/February 2020 arctic oscillation (AO) averaged +2.9 (second strongest on record) with the February AO index (+3.417) the strongest on record (for February). Identified by the vigorous +AO regime is an intense polar vortex anchored near the North Pole and strengthening the thermal ribbon in the upper atmosphere between very cold upper air in the polar region and warmer regime in the subtropics.
