LA NINA AND RAIN February 12, 2012

Over the last weeks, almost every day it has rained. Sunny days without rain have been rare.  The positive side to these circumstances is that there have not been bushfires and the water storages are relatively full.

So how can the La Nina effect be simply explained. Tom Saunders at the Weather Channel provides such an explanation:

A general indication of the amount of the rain we have had is the water flow in the creek.

According to the Bureau of Meteorology is expecting higher than median rainfall over much of Australia. They note:

“the drivers of this pattern of outlook are warmer conditions over the Indian Ocean combined with cool conditions in the topical pacific associated with La Nina.”

The following map shows the likelihood that rainfall across of Australia will exceed the median average:

In wishing for the rain to stop, there might be a time to pause to consider the alternatives that in the extreme could have been bushfires, or at least water restrictions.
