From this, we could infer that given the right circumstances, the formation of a tornado is possible. If that same storm is closer to MXX, this will allow us to "look" into the lower portion of that same storm, possibly allowing us to detect a rotational couplet closer to the Earth's surface. If the storm is a good distance away from BMX, due to the fact that the radar beam is straight and doesn't follow the Earth's surface, the lowest elevation scan from BMX may only be able to "see" into the middle portion of the storm. The example at a National Weather Service website describes it well,Ī storm between the Birmingham (BMX) and Maxwell AFB (MXX) radars (see image below). Some social media users are saying that Alexander Gleason’s 19th Century New Standard Map of the World is proof that the earth is flat and that Antarctica is not a continent. One of the fundamental concepts that we discuss is how curvature of the Earth impacts rainfall detection. I also teach a radar and mesoscale meteorology course at the University of Georgia. Believing that the Earth is flat is one of the ultimate conspiracy theories. Some of my earliest graduate work at Florida State University developed weather radar algorithms to track hurricanes. The flat earth society contains people from America and Europe and has been growing since 2009 (Wolchover 2017). Best of BBC Future Latest More The Curious Cases of Rutherford & Fry Future Video The Earth is not round (but it’s not flat either) By Adam Proctor 2nd June 2016 So what is the true shape. Weather radar: I cut my teeth as a radar meteorologist. This general circulation model is directly tied to global patterns of high-low pressure, jet streams, and weather systems. Surface winds in the polar cell are easterly (polar easterlies). At the surface air diverges outward from the polar highs. Once over the poles, the air sinks, forming the polar highs. (3) Polar cell - Air rises, diverges, and travels toward the poles. In this cell the air flows poleward and eastward near the surface and equatorward and westward at higher levels. (2) Ferrel cell - A mid-latitude mean atmospheric circulation cell for weather named by Ferrel in the 19th century. This forms a convection cell that dominates tropical and sub-tropical climates. (1) Hadley cell - Low latitude air movement toward the equator that with heating, rises vertically, with poleward movement in the upper atmosphere. Instead of one large circulation between the poles and the equator, there are three circulations. Since the earth rotates, the axis is tilted, and there is more land mass in the northern hemisphere than in the southern hemisphere, the actual global pattern is much more complicated. In reality, it is a bit more complex as described on NOAA website,
