Wont
When you look at a constant pressure surface you _______ see isotherms (Temperature varies)
Will
Horizontal divergence
A measure of percentage change in area per unit time
Vorticity
A measure of rotation or the tendency to rotate in a fluid; mathematically is the curl of the velocity vector

Circulation, closed contour, line, contour, velocity vector, velocity
Vorticity is equal to the __________ about a ______ element of area
Circulation, small
Vorticity: a _________ measure of rotation or the tendency to rotate about _______ in space
Microscopic, any point
Relative velocity (zeta)
The local component of the vorticity due to motion relative to Earth
Absolute vorticity (Etta)
Total vorticity about the local vertical axis
Planetary vorticity (f)
The local vertical component of vorticity due to Earths rotation
