Influence of the southwards shift of North American continent on North American monsoon

Abstract: The North American continent, with its large terrain and being surrounded by oceans, does not provide the setup for a large‐scale monsoon as we see in Asia. Here we examine the role of the southwards shift of the North American continent (140°–50°W, 20°–80°N) in determining North American monsoon (NAM) regions using the Community Atmosphere Model version 5.1. Results show that the meridional position of the North American continent plays a fundamental role in the existence of the NAM. When the North American c… Show more

“…As shown in Figure 10, the diabatic heating rate increases with altitude in the lower troposphere, but decreases with altitude in the mid‐to‐upper troposphere. According to Hu et al (2020), such a vertical heating structure would favour the strengthening and maintaining of the circulation pattern with the southerlies on its east and the northerlies on its west in the lower troposphere and a corresponding out‐of‐phase structure in the upper troposphere (Figure 6).…”

“…Thus, a higher MPI indicates a greater seasonal transition between wet and dry seasons. Due to the prominent dry‐wet contrast between winter and summer but relatively weak seasonal variation of wind direction in the NAM region, Hu et al (2020) noted that the MPI is much more sensitive to model simulation results than the DNS index when studying impacts of the latitude of the North American continent on associated monsoon area. Therefore, we used the MPI to investigate the change of the monsoon region over North America in our sensitivity experiments, that is, a monsoon domain is defined as the MPI value greater than 0.5 and precipitation difference between dry and wet seasons exceeding 300 mm.…”
