Unformatted text preview: ± What is the pressure gradient force? In what direction does it push? ± What is the Coriolis force? ± What is a Foucault pendulum? ± Near what latitudes is the sideways push of the Coriolis force small? Near what latitudes is it large? ± Does the Coriolis force push toward the right or left in the Northern Hemisphere? Wind Relative to Forces ± What is the wind direction relative to the location of high and low pressure? ± What is the direction of flow around a low in the Northern Hemisphere? Around a high? ± If isobars are close, what will the wind speed be? ± What does friction do to the wind speed? ± What does friction do to the wind direction? Why? ± What are convergence and divergence? ± Do you expect convergence into or divergence out of a low at the surface? Rising or sinking air above a surface low? ± For a surface high, convergence or divergence? Rising or sinking air above it?...
