HOW PRESSURE SYSTEMS CONTROL THE CLIMATE PART 1 – DECLINE IN EXTREME WEATHER

HOW PRESSURE SYSTEMS CONTROL THE CLIMATE PART 1 – DECLINE IN EXTREME WEATHER 7



The most destructive storms are convective storms like hurricanes , tornadoes, thunderstorms and heavy rainfall. This video examines where the greatest convective energy is located and why scientists are finding a decrease in extreme weather, evidence that contradicts the climate crisis narratives.

A transcript of video is available at

  1. One correction, In the video I mis-spoke regards convection in the tropics. 14,000 meters is correct but I said 14,000 kilometers. It is corrected in the transcript

  2. Ironically the atmosphere warms the planet surface like a real greenhouse – rising air cannot escape the system and returns back to the surface where it was originally warmed and carrying with it some of that energy it gained the last time it was at the surface – not by the radiatively warming "greenhouse effect" which is pseudoscience.

    The sun warms the surface, heat energy of the surface is converted to kinetic energy in the lower atmosphere, kinetic energy is converted to gravitational potential energy as it rises and converts back to kinetic energy as it falls, and some of that kinetic energy is transferred back to the surface – much of it directly converting from kinetic energy to latent heat of water vapor (most water vapor is created by wind) providing a positive feedback in the convection cycle.

  3. I wish we could know how these cells will behave in the near future. In Chile drought has been very dire during the last 5 years, because the high pressure system in front of us in the Pacific keeps getting suck during the winter, blocking rains. Again in Santiago we are rationing water, as 2021 was the 4th driest year ever recorded

  4. Very good video. One minor correction – you said, in relation to the adiabatic cooling rate, that air can travel upwards to 1400 km. 1400 km is in outer space. I think you meant 14,000 m.

  5. This video hugely increased my understanding of the highs that march on along the southern coast of Australia from Indian ocean keeping our summers dry. Always wondered where and why they are such a permanent feature.

  6. Good video thanks. Two areas that seem not quite right to me but I have read them many times in climate papers. First is the idea that latent energy is released into the atmosphere during condensation. The energy is already there but in gaseous phase. During condensation water molecules with lower average kinetic velocity are the first to condense and those with higher velocity remain in gaseous phase. The total system has the same kinetic energy but it resides in a different phase. Is that correct? So the gas air molecules partly made up of water vapor has slightly more kinetic energy and slightly less density than air outside of the cloud. That is why clouds float? Next the circulation zones, Hadley Ferrell and Polar, are circulating pulling up moist warmer air and downwelling colder dryer air after the water vapor has condensed. These cells are so stable that their convergence areas define where the world’s great deserts are. This seems to say that whatever drives or effects both the strength of circulation and the size of the cells effectively controls climate around the globe. The sun is the logical place to look and the work of Dr Brian Tinsley and Dr Henrik Svendsmark both point to solar influence of cloud formation. Climate is very complicated and your video makes a good summary of the reasons for skepticism when facing climate certainty of certain parts of the climate community.
