Climatic Background and Prediction of Boreal Winter PM2.5 Concentrations in Hubei Province, China by Yuanyue Huang, Zijun Tang, Zhengxuan Yuan, Qianqian Zhang

“…Near-surface easterlies and an anomalous anticyclonic circulation over Hubei contribute to reduced precipitation, thereby decreasing the dispersion of pollutants and leading to higher PM2.5 concentrations. (2) Significant correlations are observed between DJF-HBPMC and sea surface temperature (SST) anomalies in specific oceanic regions, as well as sea-ice concentration (SIC) anomalies near the Antarctic. …”

Potential impacts of marine fuel regulations on an Arctic stratocumulus case and its radiative response by L. F. Escusa dos Santos, L. F. Escusa dos Santos, H. C. Frostenberg, A. Baró Pérez, A. M. L. Ekman, A. M. L. Ekman, L. Ickes, E. S. Thomson

“…<p>Increased surface warming over the Arctic triggered by increased greenhouse gas concentrations and feedback processes in the climate system has been causing a steady decline in sea-ice extent and thickness. With the retreating sea ice, shipping activity will likely increase in the future, driven by economic activity and the potential for realizing time and fuel savings from using shorter trade routes. …”

Migratory behaviour of humpback whales in the southeastern Pacific under climate change by Virginie Millien, Nicole Stafiej, Fernando Félix, Hector M. Guzman
