Cause Analysis of Extreme High Temperature Weather in Nanjing in 2022 and Its Impact on Crab Breeding in the Gucheng Lake Waters

Abstract

In 2022, extreme high temperature weather occurred in Nanjing, which had a great adverse impact on aquaculture such as crabs in the waters of Gucheng Lake in Nanjing. This study analyzes the temperature situation in Nanjing in August 2022 through field survey and literature research, and compares it with the weather in the same period in history. Through the analysis of the background of global warming and the study of the atmospheric circulation during the abnormal high temperature weather, the causes of the abnormal high temperature weather in Nanjing are revealed; Study the adverse effects of high temperature weather on water temperature and oxygen content, aquatic organisms, and aquaculture, especially crab aquaculture in Gucheng Lake, and put forward corresponding countermeasures.
