[ACG24-P05] Changes in precipitation over the Arctic projected by global atmospheric models with 20-km and 60-km grid sizes
Keywords:Arctic, Global warming projection, Global atmospheric model, Precipitation
The annual mean precipitation (PAVE), the simple daily precipitation intensity index (SDII), and the maximum 5-day precipitation total (R5d) averaged over the Arctic increased in the end of the 21st century. The increases in PAVE, SDII, and R5d can be partly attributed to an increase in water vapor associated with increasing temperatures, and to an increase in the horizontal transport of water vapor from low to high latitudes. These results are consistent with Kusunoki et al. (2015).
