降水增強（Precipitation Enhancement）是指通過人工幹預手段增加特定區域降水量的科學技術，屬于人工影響天氣（Weather Modification）的核心領域。其原理基于對自然雲物理過程的調控，主要應用于緩解幹旱、增加水資源或特定生态修複需求。以下是詳細解釋：
根據世界氣象組織（WMO）的定義，降水增強是通過向雲中引入催化劑（如碘化銀、幹冰等），改變雲内微物理過程，促進雲滴或冰晶增長并加速其下落形成降水。核心機制包括：
盡管全球50+國家開展相關項目，其效果驗證仍存挑戰：

"precipitation enhancement" 是一個氣象學術語，主要有以下兩層含義：
一、人工增雨技術
指通過向雲層播撒催化劑（如碘化銀、幹冰等），改變雲中微物理過程，從而增加降水量的氣象幹預手段。這種技術常用于緩解幹旱，典型應用包括：
二、自然降水增加現象
在自然氣象學中，該詞也可指代因大氣條件變化（如溫度、濕度、氣溶膠濃度等）導緻的自然降水量增加。
詞源解析
該術語需根據上下文區分人工幹預或自然現象，在學術論文中更常見人工技術含義。
