CHARLOTTE, N.C. — Some of the most active Atlantic hurricane seasons in history all occurred during La Niña conditions.
Let’s raise our Weather IQ about the climate pattern that translates to “the girl” and how this part of the ENSO cycle affects the number of hurricanes.
What is the Enso Cycle?
The El Niño Southern Oscillation, or the ENSO cycle, affects weather around the world and starts around the equator in the Pacific Ocean.
If the average sea surface temperatures over three-month increments are half a degree celsius warmer than normal, this is considered an active El Niño. Values half a degree cooler than normal are classified as La Niña. Temperatures within half a degree of normal in either direction is considered neutral or "La Nada."
