The Washington Post wrote a [surprisingly] great article a couple weeks ago dismissing some errant "climate change experts'" claims that there was visual evidence of "global climate emergency" based on the Jet Stream crossing across the equator (as if it is a brick wall and isn't allowed to under normal circumstances). You can read the article here.
And today, we see a similar weather pattern, and I'll explain why it's interesting...but by no means an indication of climate doomsday.
Cross-Equatorial wind flow is nothing new...it happens all the time. Contrary to some folks' wild ideas, the Equator is not a brick wall...air may freely travel from one side to the other un-obstructed. What makes it interesting is what causes it to occur.
In the image to the left, twin Low Pressure systems have caused wind flow to move from the Southern Hemisphere to the Northern Hemisphere into the country of India and Sri Lanka. If you notice, the Low Pressure south of the Equator spins clockwise, while the Low Pressure north of the Equator spins counter-clockwise.
This is well known to the East Indians as the "Monsoon" (literately means "season"), which brings torrential downpours to the region.
So, climate change it is not...man-made it is not...but rather just a seasonal shift in weather. No climate emergency. In fact, it isn't even the "Jet Stream" (which is found at higher latitudes and altitudes) as these so-called "climate change experts" insist.
Each of these separate masses collide, there is a drastic clash of air pressure and density irregularities. In an effort to equalize itself, the atmosphere reacts the only way it knows how - stormy weather.
The equation is simple- Wind blows, air rises and falls, and lightning strikes due to contrasts in temperature, pressure, and air density (and they are all related according to the Ideal Gas Law in physics).
Today's severe weather, by no surprise, has occurred exactly where multiple irregularities in air masses meet...from the Front Range of the Rocky Mountains through the Smoky Mountains. Multiple storm reports can also be found through Northern Michigan as differing air masses, combined with Great Lake effects, has caused a widespread thunderstorm outbreak.
