Wind


Emissions by people heat up the air, which heats up oceans and makes winds stronger, in turn speeding up global ocean currents. This further result in stronger cyclones, stronger and higher waves and faster ocean currents.  

As discussed in an earlier post, this was confirmed by a study that found increased kinetic energy in about 76% of the upper 2,000 meters of global oceans, as a result of intensification of surface winds since the 1990s.

Below follow extracts from earlier posts on Wave Height and Wind Speed, including Surface Winds, Jet Streams and Polar Vortex.




Best wishes for 2016
Above video uses surface wind content by Climate Reanalyzer (selected daily averages and sequences of forecasts) to cover the period from December 5, 2015, to January 8, 2016.

Above video stops at January 8, 2016, when two cyclones are visible, one in the North Atlantic and another one over the North Pacific, prompting me to create the image on the right.

What causes these storms to grow this strong? Waters keeps warming up dramatically off the east coast of North America. Emissions from North America tend to extend over these waters, due to the Coriolis effect, and this contributes to their extreme warming.

The image below shows strong winds and high waves that are heading for Arctic Ocean, with waves as high as 17.18 m or 56.4 ft forecast to be moving toward the Arctic Ocean on December 13, 2015.

As warming continues, this situation can be expected to get worse, with extreme weather events hitting the Arctic Ocean with ever greater intensity.

SUPER TYPHOON GONI - WIND REACHES SPEED OF 374 KM/H

The image below shows Super Typhoon Goni approaching the Philippines on October 31, 2020 18:00 UTC at 850 mb with wind reaching speeds as high as 374 km per hour or 232 miles per hour (at green circle). Instantaneous Wind Power Density was as high as 551.5 kW per square meter. 


Earlier that day, at 12:00 UTC, Super Typhoon Goni came with waves as high as 16.09 meter or 52.8 feet (second image, at green circle), as the image below shows.

On December 22, 2022, the Jet Stream reached very high speeds over the Pacific, fuelled by high sea surface temperature anomalies. The next image shows the Jet Stream moving over the North Pacific at speeds as high as 437 km/h or 271 mph (with a Wind Power Density of 349.2 kW/m², at the green circle).
From the post 'Wild Winter Weather', at:
https://arctic-news.blogspot.com/2022/12/wild-winter-weather.html

The image below shows that the Jet Stream reached speeds as high as 455 km/h or 283 mph north of Washington on February 18, 2024 03:00 UTC, with Instantaneous Wind Power Density as high as 387.5 kW/m².


The danger is that, due to strong wind along the path of the Gulf Stream, huge amounts of ocean heat will abruptly get pushed into the Arctic Ocean, with the influx of ocean heat causing destabilization of hydrates contained in sediments at the seafloor of the Arctic Ocean, resulting in eruptions of huge amounts of methane.


Stratospheric Polar Vortex wind speeds as fast as 434 km/h (at 10 hPa) forecast for Dec 19, 2019.

Stratospheric Polar Vortex wind speeds as fast as 476 km/h or 296 mph (at 10 hPa) on January 24, 2023.
