Abstract

Purpose

Eastern Africa has a complex hydroclimate and socio-economic context, making it vulnerable to climate change-induced hydrological extremes. This review presents recent research on drivers and typologies of extremes across different geographies and highlights challenges and improvements in forecasting hydrological extremes at various timescales.

Recent Findings

Droughts and floods remain the major challenges of the region. Recently, frequent alterations between droughts and floods have been a common occurrence and concern. Research underlines the heterogeneity of extremes and the impact of climate change as increased intensity and duration of extremes. Moreover, the importance of local and antecedent conditions in changing the characteristics of extremes is emphasized.

Summary

A better understanding of these drivers and how they interact is required. Observational and modeling tools must capture these relationships and extremes on short timescales. Although there are improvements in forecasting these extremes, providing relevant information beyond meteorological variables requires further research.

不断变化的气候中的极端水文现象：东非极端水文现象综述

摘要目的东非具有复杂的水文气候和社会经济背景，因此很容易受到气候变化引起的极端水文现象的影响。本综述介绍了最近对不同地域极端现象的驱动因素和类型进行的研究，并强调了在不同时间尺度上预报极端水文现象所面临的挑战和改进之处。最近，干旱和洪水之间的频繁变化已成为一种普遍现象，并引起了人们的关注。研究强调了极端天气的异质性，以及气候变化对极端天气强度和持续时间增加的影响。此外，研究还强调了当地条件和先决条件在改变极端气候特征方面的重要性。观测和建模工具必须在短时尺度上捕捉这些关系和极端现象。尽管在预报这些极端天气方面有所改进，但要提供气象变量以外的相关信息，还需要进一步的研究。
