Four weeks of climate data: Northern Tropics Region #3

The third slice of the Northern Tropics is the Pacific Ocean on the Asian side of the International Date line.

There are islands dotting this region, but I am not certain why the easternmost column is so well represented. There are either weather stations on a bunch of very small islands from the Philippines up to Japan or some of those stations are actually at sea.

The general Winter trend is upward, but the range of change from warmest to coldest is only about one and a half degrees C.

Spring shows a warming trend, again over a very limited range. Also, the big jump was between the 1955-1975 era to the 1975-1988. The rate here looks like it's slowing down.

Summer is very much like Spring, warming but slowing down, a very small range of temperatures.

The only point of disagreeing data in Fall is that the record high was over 20 years ago.

Confidence of the region warming: 99.9%
Confidence of decreasing rate: 97.9%
Change in median temperature from the 1955-1975 interval to the 1999-2010 interval: 0.52° C

We can definitely show a warming trend overall, but it is not particularly severe and the rate is getting slower.

Later today, the Western Hemisphere slice of the tropical Pacific, which means we are taking the temperature of Hawaii.
