EAS 1600 Introduction to Environmental Sciences Class11- Smaller Scale Atmosphere Circulations Smaller Scale Atmosphere Circulations In our last discussion we looked at the role that general circulation of the atmosphere plays in maintaining the planetary energy balance. In this discussion we noted that in the mid-latitudes the general circulation is dominated by the Ferrel cells. However when we look at weather charts or meteorological satellite imagery we don’t see these cells like we see evidence of the Hadley Cells in the tropics. Today we will look at mid-latitude circulations to find out what is going on there. Mid-Latitude Circulations Model Reality Why don’t we “see” these mid-latitude Ferrel Cells? • They don’t exit in real time – They are averaged wind flows – If you average the winds over climatological periods (decades) you can “see” the Ferrel Cells Aside: How do you average winds?
