Don't let anyone try to convince you that the earth is a sphere! It's actually closer to an ellipsoid. How does your airline pilot know which direction to head when he’s over the ocean with no landmarks? How do we know the exact boundaries between parcels of land and between states and countries? These are questions we answer with geodesy (sometimes known as Geodetics Engineering): the science of how we characterize the shape and size of the earth.
Through prosthetics, makeup, and prop prowess, photographer Sandro turned Jessica Lange into eight visionary women — Frida Kahlo, Gloria Steinem, Georgia O’Keeffe, Janis Joplin, Diana Vreeland, Marlene Dietrich, Mae West, and Simone de Beauvoir.
Using supercomputers, a team lead by UW-Madison CIMSS researcher Leigh Orf, successfully recreated a monstrous supercell that produced several tornadoes in 2011, one of which registered as an EF-5 and touched down near El Reno, Oklahoma.
Simulation details: -Sequence one: The cloud field is examined from above, then from the south, during the phase of the storm where the tornado is strongest
-Sequence two: The full model domain is shown, looking from the south. The full cloud field is shown, and then zoomed twice to show highlight the difference between the size of the storm and the size of the tornado that it spawned.
-Sequence three: The cloud and rain fields are animated in time during the tornado's formation, and several minutes into the tornado's life cycle. The dark grey field is rain, and the lighter grey is cloud.
-Sequences four and five: Parcels are released near the ground during the tornado's maintenance phase where it is producing EF5-strength winds at ground level. Parcels are colored by source region.
-Sequence six: Vorticity magnitude is shown as a volume rendered field during the tornado's maintenance phase. Parcels are also released along the storm's cold pool / environment boundary near the ground, revealing the flow of the Streamwise Vorticity Current, a new feature identified in this research.
-Sequence seven: The cloud and rain field of a supercell that produces a multiple vortex EF5 tornado is animated. This sequence is from the highest resolution simulation run to date (20 meter grid spacing).
