Abstract
In this article, we examine atmospheric and river discharge conditions within the Hudson Bay Complex for the BaySys 2016–2018 field program time frame. Investigated in particular is a subset of European Centre for Medium-Range Weather Forecasts (ECMWF) Re-Analysis - Interim (ERA-Interim) atmospheric forcing variables, namely 2-m surface temperature, 10-m surface winds, precipitation, and sea-level pressure, in addition to river discharge. Results from this assessment show that 2016 was characterized by unusually warm conditions (terrestrial and marine) throughout the annual cycle; 2017 by strong cyclone activity in March and high precipitation in January, October, and November; and 2018 by cold and windy conditions throughout the annual cycle. Evaluation of terrestrial conditions showed higher than normal land surface temperatures (the Hudson Bay physical watershed) for all of the 2016–2018 period (excluding a colder than normal spell August–November 2018), particularly in January (2016 and 2017), higher than normal precipitation in October (2016 and 2017), and higher than normal terrestrial discharge to the Hudson Bay Complex in March (2016 and 2017), with drier than average June through October (2016–2018).
Highlights
Hudson Bay is an inland sea and gateway between North America and the rest of the world
As outlined in the Preface and Introduction to this special collection, the Hudson Bay System Study (BaySys) is a collaborative project focused on relative climate change and river discharge regulation impacts on freshwater–marine coupling in the Hudson Bay Complex (HBC)
Rankings and extreme atmospheric and discharge conditions The ranking in atmospheric variables sea-level pressure (SLP), surface winds, surface temperature, and precipitation spatially averaged over the HBC over the 1981–2018 time frame (Figures 15 and 16) highlights whether a particular month or season during the BaySys baseline 2016–2018 time frame is characterized by extreme atmospheric conditions relative to the 1981–2010 time frame
Summary
Hudson Bay is an inland sea and gateway between North America and the rest of the world. This paper and the companion paper (Lukovich et al, n.d.) provide a baseline evaluation of atmospheric, discharge, and sea ice conditions in the HBC during the 2016–2018 BaySys time frame.
