Plots of precipitation and low clouds. The precipitation can be compared to the observations, which can be seen here (Simona B.).
Six different GCM experiments are included for now.
- Control, run at NCAR during development of CAM v. 3. It uses monthly mean SST and is averaged over 6 years.
- Convective Precipitation Rate (m/s), note that the maximum value of the color bar is around 10 mm/day.
- Vertically-integrated low cloud fraction.
- No Mountains. Same SSTs as Control, but with the surface elevation set to sea level. Averages are again based on 6 years.
- Convective Precipitation Rate (m/s), note that the maximum value of the color bar is around 10 mm/day.
- Vertically-integrated low cloud fraction.
- No mountains with zonal mean SST. The SSTs from above are averaged over the year and over latitude bands, with the resulting zonally symmetric SST prescribed as the lower boundary. Topography is still neglected. Averages are based on 4 years.
- Convective Precipitation Rate (m/s), note that the maximum value of the color bar is around 10 mm/day.
- Vertically-integrated low cloud fraction.
- Aqua planet. SSTs are prescribed using an analytic expression equatorward of 60 degrees latitude, set to 273 K poleward of 60. No continents, no seasonal variations, equinocal conditions, including a diel variation in insolation. Averages are based on about 36 months.
- Convective Precipitation Rate (m/s), note that the maximum value of the color bar is around 10 mm/day.
- Vertically-integrated low cloud fraction.
- Aqua planet with SST increased by 2 K equatorward of 60.
- Convective Precipitation Rate (m/s), note that the maximum value of the color bar is around 10 mm/day.
- Vertically-integrated low cloud fraction.
- Aqua planet with SST decreased by 2 K equatorward of 60.
- Convective Precipitation Rate (m/s), note that the maximum value of the color bar is around 10 mm/day.
- Vertically-integrated low cloud fraction.
