Chapter 5 The circulation of the OceansThe Ocean - correct answer Have high heat capacity. So, slight differences in incoming solar radiation from place to place have little impact on surface temperature of ocean (lateral temperature and density differ slightly). The Ocean - correct answer Therefore, the ocean does not circulate as a direct response to surface heating. Wind Stress - correct answer Wind over ocean causes friction at surface --> wind-drift currents (force of wind acting o...

Clouds and precipitation are frequently found on the downwind side of a large lake. This would indicate that the air on the downwind side is a. diverging and sinking b. diverging and rising c. Stable and rising d. converging and rising e. converging and sinking - Answer-e. converging and sinking A geostrophic wind is a wind that results from a balance between the ( ) force and the ( ) force. a.

What is a constant pressure surface? - Answer Maps that show areas of constant pressure, similar to constant height maps How are low and high heights related to temperatures below that pressure surface? - Answer Low heights mean cool air below High heights mean warm air below How do you identify ridges and troughs on an upper air map? - Answer Ridges have are at the top of a hill Troughs are at the bottom, like a valley What is the pressure gradient force? In what direction does it ac...

any force has 2 measurable characteristics magnitude (size or strength) and direction Pressure Gradient Force (PGF) the gradient of any physical quantity is a measure of the difference in the value of that quantity at two different locations divided by the distance between those two locations PGF Equations X2 - X1 / D PGF moves from high pressure to low pressure isobars same pressure so PGF is perpendicular to isobars here Coriolis Effect the effect that ...
