Abstract

In the year 2023, the Earth experienced the highest near‐surface temperature anomalies ever recorded until then. In addition, several extreme weather and climate events occurred around the world, including in Brazil. In this context, the primary objective of this study is to analyze the anomalous temperature and precipitation patterns observed in Brazil during 2023, along with the most significant extreme events. Different datasets and methodologies were applied. The north coast of the state of São Paulo had the highest accumulation of rainfall recorded in Brazil in a single day. September, October, and November 2023 experienced the large precipitation deficits over the Amazon region, leading to a very intense and prolonged drought. The south of Brazil was affected by a large amount of precipitation in a short time, associated with cyclones, resulting in fatalities and economic losses. Southeast and Central‐West Brazil experienced two intense heatwaves in the austral spring, breaking daily temperature records in major cities like São Paulo and Rio de Janeiro. Overall, this study describes the main physical processes responsible for these extremes, along with the socioenvironmental impacts caused by most of them.

巴西气候突出2023年

2023年，地球经历了有记录以来最高的近地表温度异常。此外，包括巴西在内的世界各地发生了几起极端天气和气候事件。在此背景下，本研究的主要目的是分析2023年巴西观测到的异常温度和降水模式，以及最显著的极端事件。采用了不同的数据集和方法。圣保罗州北部海岸的降雨量创下了巴西单日最高记录。2023年9月、10月和11月，亚马逊地区经历了大量降水不足，导致了非常严重和持续的干旱。巴西南部在短时间内受到与旋风有关的大量降水的影响，造成人员死亡和经济损失。巴西东南部和中西部在南部春季经历了两次强烈的热浪，在圣保罗和里约热内卢等主要城市打破了每日温度记录。总体而言，本研究描述了导致这些极端天气的主要物理过程，以及其中大多数极端天气造成的社会环境影响。
