Impacts of Sea Surface Temperature and Atmospheric Teleconnection Patterns in the Northern Mid-Latitudes on Winter Extremely Cold Events in North China

<div>The lead-lag and contemporaneous correlation coefficients between the frequency of the winter SSECEs in North China and the SSTA in spring (a), summer (b), autumn (c), and winter (d). Shaded areas represent statistical significance at the 90% confidence level using Student’s <i>t</i>-test and the rectangles with A, B, and C are the SST key areas.</div>
