  1. ATOC 4720: class 6: Winds and precipitation • 1. Winds • Scales of motions • Longitudinally averaged zonal winds • Tropospheric winds at different latitudes • 2. Precipitation

  2. Class 5: The temperature distribution and its measurement Sharp drop In water 80% mass All water (homo or heter?)

  3. 1. Winds in the earth’s atmosphere • Spatial scales of motion: • (1) Planetary-scale; • (2) Synoptic-scale (~a few hundreds of km); • (3) Meso-scale (a few tens of KM~hundreds km); • (4) Small-scale (< a few 10km).

  4. Planetary scale winds: zonal mean

  5. Winds in tropical stratosphere

  6. Winds in troposphere: middle & high latitudes

  7. Surface Pressure

  8. Winds in the tropics

  9. Easterly wave Perturbation

  10. Asian-summer monsoon

  11. 2. Precipitation

  12. Precipitation January

  13. July
