They altered the deal on Vader's helmet (jpeg & gif comparison) (self.StarWars) submitted 4 months ago by pldkn. In a previous Japanese trailer, we could see Darth's menacing pose as he turns to the camera - but mostly I saw his awkward neck situation. In a new Chinese trailer, they show the same shot again, but this time it's obviously edited. No more weird neck situation, much more sinister looking indeed.
Air parcels, in a horizontal air pressure gradient, flows in a direction to eliminate the pressure gradient. The force that causes air parcels to move as the consequence of an air pressure gradient is known as the pressure gradient force and always acts directly perpendicular to isobars and toward lowest pressure.
Figure 1 The uneven heating of Earthâs surface produces pressure belts. These belts occur at about every 30Â° of latitude. What causes wind? The Coriolis Effect At the equator, Earthâs surface receives a lot of direct sunlight that heats the ground and the air. As a result, air pressure is low at the equator.
