They have investigated the long-term change of the Hadley cell rotation as an expression of the climate hazards associated with the global warming trend over the past half century. By placing most of the arid regions around the earth beneath the substrate branches of the Hadley cells, it indicates the expansion of the subtropical arid zone that results in a drier subtropical climate. Ultimately, this may lead to more desertification than existing boundaries, and the consequences for those areas whose climate is affected by these features are important to manage. In this study, the European Mid-Term Forecast (ECMWF) Version (ERA5) reanalysis forecast data with 0/25 * 0/25 spatial resolution and 40 years interval (1979-2018) from the output long wave radiation data Ground, sea level pressure, evaporation and precipitation, zero-level orbital wind, tropical jet, jet velocity curve, tropopause gap, and meridional flow function using MATLAB software to investigate Hadley cell rotation polarization in the southern hemisphere Been paid. Most of the Hadley cell rotation criteria have been increasing since 1979. Hadley cell latitude with sea level pressure criteria in summer, winter, autumn and spring 1 to 3 degrees latitude, evaporation minus 1 to 3 degrees latitude, zero orbital level 1 to 2 degrees latitude, tropical jet 1 Up to 3 degrees latitude, jet speed curves 1 to 3 degrees latitude The findings showed that with increasing each year, the width of the Hadley cell with the meridional flow function function increased by -0/032 ° C on average. Overall, this study shows that Hadley cell rotation in the southern hemisphere increased by 1 to 3/5 degrees latitude, and since 1999, the intensity of the increasing trend of Hadley cell rotation in the southern hemisphere has been more pronounced. The highest increase in the latitude of Hadley's cell rotation during 1999, 2001, and 2011 extended to a latitude of -33/5 ° C, showing evidence of the expansion of the Hadley cell's rotation toward the pole, increasing drought and water hazards. And it has the air ahead.
