The coriolis force - Study guides, Class notes & Summaries

How can you identify a region of strong pressure gradient on a weather map? What does strong pressure gradient imply about the strength of wind? Answers- When isobars are closer then there is a higher pressure gradient. That means the winds are stronger where pressure gradient is highest What are the forces that act on the air to make wind blow? Answers- - The pressure gradient is the source for all wind. - Air moves from high pressure to low pressure In the Northern Hemisphere, why do w...

WX 201 Exam 2 with correct Answers (Graded A) Generally, the concentration of condensation nuclei is greater over the oceans than over land. False If a city receives 24 inches of snow, it is the equivalent to 18 inches of rain. False An important factor in the production of rain by the collision-coalescence process is the number of ice crystals in the cloud. False In a cloud composed of water droplets and ice crystals, the saturation vapor pressure is less over the droplets th...

GEOG 1900 Final Exam with Complete Solutions The forces involved in surface winds and in geostrophic winds Eddy viscosity Geostrophic winds Eddy viscosity Friction associated with the dissipation of kinetic energy due to eddies. The rougher the surface, the greater the eddy viscosity. The eddy viscosity decays rapidly with the height above the Earth's surface so that the horizontal winds strengthen with the height. Geostrophic winds upper-level winds (the balance between the horizonta...
