THE CLIMATE KELPIE BLOG: What’s predicted in February

Posted by BCG on 4th February 2019

BoM have moved their ENSO Outlook status down to El Niño watch which means there is still a 50 per cent chance of an El Niño forming.

Historically, now is the traditional time for climate drivers like the El Niño Southern Oscillation and the Indian Ocean Dipole to reset for the coming season, therefore skill of the model at this time of the year is lower.

Rainfall Roundup

January was very dry with large areas highlighted in red in figure 1 showing below average to lowest on record rainfall for the month.

The last three-month deciles in figure 2 show that significant falls in December for some areas have increased the overall three-month decile, therefore showing what a difference a significant rain event can have.
