Monday Lecture, 4/4 Changes in pressure: o Winds flow from colder air to warmer air in surface SLOWER o Winds flow from warmer air to colder air in the atmosphere FASTER Isoheights used to measure pressure values in the upper atmosphere Wind types: o Geostrophic wind No turning involved = isoheight lines are parallel Wind is moving at a constant speed PGF initiates wind flow Coriolis will fall to the right o Gradient wind Higher altitudes cause higher pressure o Supergeostrophic Upward arc of warmer air working its way North Wind turns to the RIGHT PGF points away from the high, coriolis force points opposite of PGF Coriolis force is greater in magnitude then the PGF because it falls left and works its way right to turn Warm air intruding from warmer latitudes to higher latitudes o Subgeostrophic Downward arc, colder air advancing Southward PGF points towards low, coriolis force falls to the right because it makes a left turn PGF is greater in magnitude than coriolis force Surface vs. upper level winds o Wind will naturally want to flow from the equator to the poles o Northern hemisphere Wind will typically flow Westerly Centrifugal force vector will always point away from center Friction will not be drawn in atmosphere wind diagrams because there is no dynamic that will cause friction in the atmosphere Wednesday Lecture, 4/6 TOPIC 11 Thunderstorms rain with thunder and lightening o Rising and sinking motions cause collisions between ice crystals, which then causes lightening o 10,00020,000 degrees Celsius Africa has the most thunderstorms U.S largest average number of lightning strikes is in Tampa, Florida 4 thunderstorm ingredients o Lifting (all the different types discussed in topic 7) o Instability o Wind shear Vertical wind shear (causes INTENSE thunderstorm conditions) Change in wind speed with height Updraft vs. downdraft in a thunderstorm Updraft Upward moving air currents Downdraft Downward moving air currents Wind direction turning with height o Moisture Feeds into the thunderstorms Moisture is gained through maritime air masses Another thunderstorm formation factor o Low Level "Jet" Stream (Nocturnal jet) During night time hours, warm and moist air can flow more efficiently, making the winds flow faster and stronger
