Geostrophic winds Study guides, Class notes & Summaries

What is the source of almost all energy in the Earth system? - Answer-Solar Radiation (the sun) Explain the Earth's radiation balance at the top of the atmosphere. - Answer-Qin=Qout (incoming energy must equal outgoing energy) Explain the Earth's surface heat budget. What terms are the most important? - Answer-100 units of solar radiation at the top of the atmosphere, approximately 25% is reflected back to space, 25% is absorbed by the atmosphere, and 50% reaches Earth's surface. Of that...

UCLA A&O3 Midterm Latest Update Graded A The atmosphere is a mixture of gas molecules, small particulates, and moisture Technological advances in computer hardware and software have had a huge impact on our ability to understand and predict the weather Radiosondes allow us to measure weather conditions in the upper atmosphere A network of surface and upper-air observations is crucial to meteorological understanding because organized weather systems often cover large areas The invention of th...

1 ATSC 310- TEST 1 EXAM | QUESTIONS & ANSWERS (VERIFIED) | LATEST UPDATE | GRADED A+ Forecasting steps Correct Answer: Assess present. (6 hr surface, 12 hr sounding) Predict future. Interpret results. Forecasting Methods Used Correct Answer: Climatology- baseline expectations Analogue- historically similar conditions Persistence- future like present Trends/Extrapolation- future will be like upwind wx Numerical Wx Prediction Ensemble Forecast Empirical Pattern- rules of thumb E...

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...

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...

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. Coriolis; pressure gradient b. Coriolis; gravitational c. pressure gradient frictiona...

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 ...

One way to change air pressure is to.. - ANSWER-move up or down in the atmosphere Pressure decreases with.. - ANSWER-height Can a plane door really be opened while in flight? - ANSWER-Cant open the door, they open in first and then open out Air pressure outside of the plane is very low, the cabin pressure is much greater Adding cold air to an air column will.. - ANSWER-shorten the column Adding warm air to an air column will.. - ANSWER-expand/make the air column taller Horizont...

Constant Pressure - Answer A surface in the atmosphere where the pressure is equal everywhere along that surface Higher heights=____;Lower heights=____. - Answer Warmer air;colder air Isotherms - Answer Lines of equal temperature Ridges - Answer Elongated highs where air is warmer and indicating depressions Troughs - Answer Elongated lows where air is colder. Pressure gradient force (PGF) - Answer Directed from higher towards lower pressure at right angles to the isobars; force th...
