    The diurnal cycle of precipitation is important to the hydroclimate in the Himalayas in summer; however, features of the diurnal cycle that affect precipitation from the foothills to glacierized, high-elevation areas are poorly understood. We investigated the diurnal cycle of precipitation using 3 years of in situ observations recorded close to a glacier at 4,806 m asl, and 17 years of data from the Tropical Rainfall Measuring Mission (TRMM) precipitation radar (PR) and the Integrated Multi-satellitE Retrieval for Global Precipitation Measurement (IMERG). The mechanisms that drive the diurnal cycle were examined using hourly European Center for Medium-Range Weather Forecasts Re-Analysis fifth generation (ERA5) data. In situ observations showed that the diurnal precipitation cycle has daytime and nighttime peaks, which both consist of high rainfall frequency and low rainfall intensity. In addition, twice-daily maxima exist in the TRMM PR data, particularly over two rain bands at around 500–1,000 m asl, and at ∼2,000 m asl. Convective-type rainfall, with a lower rain-top height, occurs in the daytime, whereas stratiform-type rain, with a higher rain-top height, occurs at night, particularly over terrain at elevations above ∼1,500 m asl. Land surface processes likely cause the two peaks in the diurnal cycle. Daytime surface heating drives upslope flows that promote condensation. At night, surface cooling over the plain to the south of the Himalayas causes low-level monsoon flows to accelerate, creating a nocturnal jet, which results in large-scale moisture flux convergence over the southern slopes.

    アジアならではの大気陸面相互作用を、1) ヒマラヤ・チベットなどの山岳が作り出す地形性の大気陸面相互作用、2) インドネシア・マレーシアに代表されるような長い海岸線を挟んでの大気陸面相互作用、3) 日変化および季節内変動が気象擾乱の時間スケールとして卓越する中での大気陸面相互作用、の3要素から再構築する。これらは現時点での教科書的な大気陸面相互作用「像」あるいは「観」には含まれていない。また、決して鉛直一次元的な解釈には収まらない。本研究はで、地上観測データ、人工衛星データ、数値シミュレーションを複合的に利用することによって、アジア大気陸面相互作用について上記3つの視点からの解明を試みる。
