Research on the influencing factors of the difference in warming rates between the east, west and central regions of North America during the 21st century

Abstract

Temperature in North America (NA) is a significant focus of current climate change research. This study focuses on various climate variables and employs linear regression and correlation coefficient analysis to examine the factors influencing the differences in warming rates across the eastern, western, and central regions of NA in the 21st century, as well as the correlations between these factors and temperature. Results indicate that NA temperatures are rising with notable regional variations in warming rates. Under the influence of cloud cover, the impact of precipitation on warming rates is relatively minor, whereas radiation significantly affects warming rates. Additionally, sea level pressure influences wind patterns, thereby significantly impacting warming rates. This study highlights the complexity of regional climate dynamics in NA and provides deep insights into regional climate differences.
