What is the Walker Circulation? The El Niño Southern Oscillation, or ‘ENSO’, is one of the major causes of year to year variability in Earth’s climate. ENSO is characterised by: changes in the temperature of the ocean’s surface in the tropical Pacific Ocean, and by changes in atmospheric circulation in an east-west direction above the Pacific Ocean. Number two in that list is what makes ENS ...[Read More]
