Abstract Changes in the extreme annual wind speed and around Gulf of St. Lawrence (Canada) were investigated through a nonstationary value analysis maximum 10-m obtained from North American Regional Reanalysis (NARR) dataset as well observed data selected stations Environment Canada. A generalized distribution with time-dependent location scale parameters was used to estimate quantiles interest functions time at locations where significant trend detected.

The West Africa rainfall regime constitutes a considerable challenge for Regional Climate Models (RCMs) due to the complexity of dynamical and physical processes that characterise African Monsoon. In this paper, daily precipitation statistics are evaluated from contributions AFRICA-CORDEX experiment two ERA-Interim driven Canadian RCMs: CanRCM4, developed at Centre Modelling Analysis (CCCma) CRCM5, University Québec Montréal. These modelled against three gridded observed datasets—the Global...

Since the 1980s, populations of Asian tiger mosquito Aedes albopictus have become established in south-eastern, eastern and central United States, extending to approximately 40°N. Ae. is a vector wide range human pathogens including dengue chikungunya viruses, which are currently emerging Caribbean Central America posing threat North America. The risk expanding its geographic under current future climate was assessed using three climatic indicators survival: overwintering conditions (OW), OW...

This study investigates temporal evolution of 1‐, 7‐, 15‐, and 30‐day annual seasonal low‐flow regimes pristine river basins, included in the Canadian reference hydrometric basin network (RHBN), for three time frames: 1974–2003, 1964–2003, 1954–2003. For analysis, RHBN stations are classified into categories, which correspond to where low flows occur winter only, summer both seasons, respectively. Unlike previous studies RHBN, such classification is essential better understand interpret...

Droughts are among the world's most costly natural disasters and collectively affect more people than any other form of disaster. The Canadian Prairies very susceptible to drought have experienced this phenomenon many times. However, recent 1999–2005 Prairie was one worst meteorological, agricultural hydrologic droughts over instrumental record. It also had major socio-economic consequences, adding up losses in billions dollars. This focus Drought Research Initiative (DRI), first integrated...

Abstract Gridded estimates of precipitation using both satellite and observational station data are regularly used as reference products in the evaluation basic climate fields derived indices simulated by regional models (RCMs) over current period. One issues encountered RCM is fact that RCMs usually on different grids often at horizontal resolutions. A proper requires remapping a common grid. For or other fields, can be done two ways: either first-step operation original field with index...
