I was reading and article by Max Gongalez of weatherzone news
about the possibility of an El Nino in 2014
(the warm phase) occurs when warmer than average sea surface temperatures (SSTs) prevail over the central and eastern equatorial Pacific Ocean (from late winter to late autumn),
accompanied by high atmospheric pressure over the western Pacific.
This high atmospheric pressure typically leads to lower than average rainfall over Australia during El Nino years.
La Nina(cool phase) on the other hand, occurs when cooler than average SSTs prevail over the central and eastern equatorial Pacific.
This is accompanied by a low atmospheric pressure over the western Pacific,
thus typically bringing above average rainfall to mainland Australia during La Nina years.
I thought l would follow this ENSO season by testing this hypothesis/ fact
I will post the global MSLP ( mean sea level pressure) anomalies in the Pacific every month and observe the changing surface MSLP anomaly pattern
The February 2014 MSLP anomalies show low pressure anomalies in both the east and west basin. Although there is a band of high pressure over Australia and the far west basin of the pacific
According to theory .. Low pressure in the east basin is a la Nina indicator
I’m not sure?
I thought low pressure was a symptom of warm SST anomalies..?
I will post MSLP updates each month for 2014 in the comments section below
