Abstract. With semiconductor technology gradually approaching its physical and thermal limits, recent supercomputers have adopted major architectural changes to continue increasing the performance through more power-efficient heterogeneous many-core systems. Examples include Sunway TaihuLight that has four management processing elements (MPEs) 256 computing (CPEs) inside one processor Summit two central units (CPUs) six graphics (GPUs) node. Meanwhile, current high-resolution Earth system...
Abstract With a pair of high‐resolution (HR, 10 km ocean and 25 atm) low‐resolution (LR, 100 Community Earth System Model (CESM) simulations, we investigate compare the long‐term mean Northern Hemisphere (NH) wintertime storm tracks against reanalysis data. Based on several Eulerian measures, CESM‐HR shows poleward shift NH reduced equatorward bias in North Pacific relative to CESM‐LR. Those may be associated with refined topography Tibetan Plateau as well improved subtropical jet,...

The binary typhoon systems of Lekima and Krosa (2019) have been simulated using the Weather Research Forecast (WRF) model with 27 km, 9 3 km resolutions their behaviors moist potential vorticity (MPV) in these simulations analyzed. All clearly show that main sources instability energy include two parts MPV—the convective from environmental field (MPV1) internal transferring between typhoons (MPV2). While absorb upper ocean through vortex effects on periphery as external MPV sources, there is...
Abstract The primary sources of predictability the Earth climate system come from initial conditions and external radiative forcings, which is a joint initial-boundary-value problem. It crucial to clearly understand contributions forcings (i.e. initial-value boundary-value) total predictability, for traditional study examines growth uncertainties however difficult quantitatively identify. This uses variations prediction skills in space lead times systematically linear behaviors...
