亚洲降水实验（AsiaPEX）于2019年启动，目的是在全球水文气候专门委员会(GHP)/全球能源和水交换（GEWEX）的框架下，了解不同水文气候条件下的陆地降水，以改进亚洲的预测、减灾和可持续发展。AsiaPEX是继GEWEX亚洲季风试验（GAME, 1995-2005）和亚洲季风水文大气科学研究与预测计划（MAHASRI, 2006-2016）之后的项目。在保留上述项目的主要目标的同时，AsiaPEX的科学目标侧重于陆地-大气耦合和提高亚洲水文气候系统的可预测性。AsiaPEX既考虑了发生在陆地表面的精细尺度水文气候过程，也考虑了具有多尺度相互作用特征的亚洲综合水文气候系统。我们采用了六种方法，包括观测、过程研究、尺度相互作用、高分辨率水文模拟、野外活动和气候预测，弥补了不同地区研究活动的差距。与中尺度和全球模式研究人员合作是AsiaPEX的核心方法之一。我们根据文献和我们的初步结果来回顾这些策略。这些研究包括高分辨率卫星降水的估计和验证、极端降雨机制的调查、海洋大陆和青藏高原的野外运动、对整个亚太地区有重大影响的地区、日至年代际尺度相互作用的过程研究，以及气候模式长期变化的可预测性评估。我们将在2025-2028年前后开展亚洲季风年(AMY)-II综合观测和模拟倡议，其战略是分区域观测平台和综合全球分析。
The Asian Precipitation Experiment (AsiaPEX) was initiated in 2019 to understand terrestrial precipitation over diverse hydroclimatological conditions for improved predictions, disaster reduction, and sustainable development across Asia under the framework of the Global Hydroclimatology Panel (GHP)/Global Energy and Water Exchanges (GEWEX). AsiaPEX is the successor to GEWEX Asian Monsoon Experiment (GAME, 1995-2005) and Monsoon Asian Hydro-Atmosphere Scientific Research and Prediction Initiative (MAHASRI, 2006-2016). While retaining the key objectives of the aforementioned projects, the scientific targets of AsiaPEX focus on land-atmosphere coupling and improvements to the predictability of the Asian hydroclimatological system. AsiaPEX was designed for both fine-scale hydroclimatological processes occurring at the land surface and the integrated Asian hydroclimatological system characterized by multiscale interactions. We adopt six approaches including observation, process studies, scale interactions, high-resolution hydrological modeling, field campaigns, and climate projection, which bridge gaps in research activities conducted in different regions. Collaboration with mesoscale and global modeling researchers is one of the core methods in AsiaPEX. We review these strategies based on the literature and our initial outcomes. These include the estimation and validation of high-resolution satellite precipitation, investigations of extreme rainfall mechanisms, field campaigns over the Maritime Continent and Tibetan Plateau, areas of significant impact on the entire AsiaPEX region, process studies on diurnal to interdecadal scale interactions, and evaluation of the predictabilities of climate models for long-term variabilities. We will conduct integrated observational and modeling initiative, the Asian Monsoon Year (AMY)-II around 2025-2028, whose strategies are the sub-regional observation platforms and integrated global analysis.
