Can GCM simulate the timing of diurnal cycle?

(Arakawa & Kitoh)

• 20km AGCM captures spatial

distribution of diurnal rainfall peak time over both land and the ocean within a few hours

• Few difference between 20km and

120km AGCMs

Objective of AMY Objective of AMY’ ’08 08

• To improve Asian monsoon predictions, in

particular, in intraseasonal and seasonal time scales To attain its goal….

• Clarify multi-scale interactions among diurnal,

synoptic and intraseasonal variations of Asian monsoon

• Clarify land surface processes related with

Asian monsoon variability

• Clarify the role of aerosol on Asian monsoon

variability
