In this study, the annual and seasonal climatology of cloud fraction (CF) type simulated by Canadian Environmental System Models (CanESMs) version 5 (CanESM5) 2 (CanESM2) at their fully coupled AMIP configurations were validated against CALIPSO-GOCCP-based CF. The CFs produced using CALIPSO-COSP simulator based on CanESMs data atmospheric (AMIP) configuration are also evaluated. shortwave, long...

This study focused on the Upper Manyame sub-catchment which covers an area of approximately 3 786 km2 and forms part catchment, one seven catchments Zimbabwe. catchment has its source in Marondera town drains into Zambezi River downstream Kariba Dam upstream Cahora Bassa Dam, northern country. assessed potential climate change impacts streamflow reservoir inflows sub-catchment. Hydrologic simul...

The overarching objective of this study was to evaluate the performance nine precipitation-based and twelve temperature-based climatic indices derived from four regional climate models (CRCM5-UQUAM, CanRCM4, RCA4 HIRHAM5) driven by three global circulation (CanESM2, EC-EARTH MPI-ESM-LR) their ensemble mean for reference period 31 years (1975–2005). absolute biases, pattern correlation, reductio...

Abstract Due to the significant negative consequences of winter cold extremes, there is need better understand and simulate mechanisms driving their occurrence. The impact atmospheric blocking on spells over North America investigated using ERA-Interim NCEP-DOE-R2 reanalyses for 1981–2010. Initial-condition large-ensembles two generations Canadian Earth System Models (CanESM5 its predecessor, C...

Abstract As summer heatwaves have severe adverse impacts on human society and ecosystems, there is need to better understand their meteorological drivers future projections under climate change. This study investigates the linkage between atmospheric blocking (June–August) over North America using two reanalysis datasets (ERA-Interim NCEP-DOE-R2) large-ensembles of Canadian Earth System Models ...

Abstract. The newest iteration of the Canadian Earth System Model (CanESM5.0.3) has an effective climate sensitivity (EffCS) 5.65 K, which is a 54 % increase relative to model's previous version (CanESM2 – 3.67 K), and highest all current models participating in sixth phase coupled model inter-comparison project (CMIP6). Here, we explore underlying causes behind CanESM5's increased EffCS via co...

Abstract Climate change is a complex and multi-layer issue with global local entanglement. In this study, Langat River Basin chosen. Secondary data was used including the historical flood drought event reports, Standardized Precipitation Index-1 Canadian Earth System Model (CanESM2) along Australian Community Simulator Coupled (ACCESS CM-2). These were to determine monthly precipitation risk ba...
