00:00:00.730 --> 00:00:06.640
NASA scientists say a La Nina is unlikely in 2016-2017.

3
00:00:06.660 --> 00:00:10.200
After a warm El Nino last winter

4
00:00:10.220 --> 00:00:13.980
forecasts show the central Pacific will not get cold enough

5
00:00:14.000 --> 00:00:17.980
to switch to a La Nina this year.

6
00:00:18.000 --> 00:00:23.880
The forecast is based on NASA satellite data

7
00:00:23.900 --> 00:00:30.430
combined with measurements of winds, temperatures, and more.

8
00:00:30.450 --> 00:00:34.300
That's nine terabytes of data

9
00:00:34.320 --> 00:00:39.490
running on supercomputers for 18 hours at a stretch

10
00:00:39.510 --> 00:00:47.080
to produce a forecast for the next 9 months.

11
00:00:47.100 --> 00:00:50.010
"We are consistently predicting a neutral state

12
00:00:50.030 --> 00:00:54.380
no La Nina nor El Nino this year," said Steven Pawson, NASA scientist.
