Abstract
Conclusions:
Impact of downscaling is very limited
- Significant enhancement of deepening rate
- historical: 1.5 hPa per 24 hrs
- RCP8.5: 2.3 hPa per 24 hrs
Potential main bias source is a weak meridional temperature gradient
Explosive ETC precipitation is projected to increase
- 49% GCM, 43% RCM
- Consistent with increase in specific humidity
