Winds keep changing as warming continues
On the image below, cyclonic winds on December 21, 2017, are visible near the Philippines and Vietnam. Near the Philippines, 3-hour precipitation accumulation was as high as 121.6 mm or 4.79 in (at green circle). As a BBC report describes, Tropical Storm Tembin made landfall in the southern Philippines on December 22, 2017, causing flash flooding and mudslides. More than 180 people are reported to have been killed, as the tropical storm swept through Mindanao island, with dozens more missing.
A week earlier, Tropical Storm Kai-Tak hit the central Philippines, killing dozens. The region is still recovering from Typhoon Haiyan, which killed more than 5,000 people and affected millions in 2013.
The winds are fueled by high sea surface temperatures. Above image shows that, on December 21, 2017, sea surface temperatures were as high as 31.7°C or 89°F north of Australia. In line with rising temperatures caused by global warming, sea surface temperature anomalies are high across the oceans, as the image below illustrates.
As above image also shows, the sea surface was relatively cold at locations indicative for El Niño (depicted as four El Niño regions on the right).The image below shows El Niño forecast plumes indicating that we're currently in a La Niña period, and that temperatures are on the rise.
In conclusion, just like the rise in temperatures is currently masked by a La Niña period, the return to a new El Niño period will further strengthen the rise.
This strengthening of winds in what can be expected in a warmer world. As the images above, to the right and below further illustrate, changes to Jet Streams and winds can cause a lot of heat to be brought into the Arctic, through the Bering Strait and the Fram Strait.The importance of Arctic warming was discussed earlier, e.g. in the post Warming is accelerating. As the jet stream becomes more wavy and extends over the Arctic, more warm air and water gets carried into the Arctic, further speeding up warming, as also discussed at The Arctic is changing the Jet Stream - Why This Is Important.
This further confirms the updated trend analysis of the NASA temperature anomaly below.
The situation is dire and calls for comprehensive and effective action, as described in the Climate Plan.
