Wind gusts are rare bursts of high wind, often associated with thunderstorm outflows. They can do significant structural damage, and their rarity and small scale make prediction and risk assessment difficult. This proposal seeks to better understand and predict wind gusts and their impacts to aid in planning. The project aims to use past observations, modelling, and basic theory to show what conditions lead to wind gusts and how likely they are to exceed key thresholds. It targets important scientific and practical issues such as the joint occurrence of gusts and high rainfall, role of gusts in contributing to dust and other airborne pollutants, impacts of gusts on subsequent storm activity, and gusts in a warming climate.

阵风是罕见的大风，通常与雷暴气流有关。它们可以造成严重的结构破坏，而且它们的罕见性和小规模使得预测和风险评估变得困难。该提案旨在更好地了解和预测阵风及其影响，以帮助规划。该项目旨在利用过去的观测、建模和基础理论来显示导致阵风的条件以及它们超过关键阈值的可能性。它针对重要的科学和实际问题，如阵风和强降雨的共同发生，阵风对灰尘和其他空气污染物的作用，阵风对随后的风暴活动的影响，以及气候变暖中的阵风。
