Three parallel black curved lines sweep across the central part of the country from west to east. The map highlights a light blue oval-shaped area, intersected by these curves, moving from west to east across the screen. Small red squares move along the curved lines and speed us as they round the base of the trough, depicting air parcel movement. The background features faint outlines of U.S. state borders.

The animation shows a diagram illustrating atmospheric vorticity concepts. Two sets of curved black lines with labeled features are overlaid on a white background. The lines represent atmospheric flow patterns. Among them, there are dashed red lines creating oval shapes, indicating vorticity gradients. To the left, a green gradient highlights an area labeled with a box containing text about "increasing vorticity" and "convergence." To the right, a blue gradient highlights an area labeled with a different box containing text about "decreasing vorticity" and "divergence". A small square moves across the isobars from left to right, getting smaller and speeding up as it rounds the bottom of the trough.

Transcribed Text:

Left box: "As parcels move towards the trough axis, they move into an environment of increasing vorticity. In order to maintain equilibrium with their surroundings, parcels must also increase vorticity. The only way that they can do this is to undergo convergence."

Right box: "As parcels move away from the trough axis, they move into an environment of decreasing vorticity. In order to maintain equilibrium with their surroundings, parcels must also lose vorticity. The only way that they can do this is to undergo divergence."

The image shows a vast, arid desert landscape with a rough, rocky surface stretching into the distance.
