TL;DR: A high-resolution 10Be chronology of glacier fluctuations in New Zealand’s Southern Alps over the past 7000 years, including at least five events during the last millennium is presented, suggesting that atmospheric circulation changes in the southwest Pacific were one important factor in forcing high-frequency Holocene glacier fluctuations.

TL;DR: In this paper, the authors synthesize some common synoptic and mesoscale environments conducive to heavy orographic rainfall, including a conditionally or potentially unstable airstream impinging on the mountains, a very moist low-level jet (LLJ), a steep mountain, and a quasi-stationary Synoptic system to slow the convective system over the threat area.

TL;DR: In this paper, the authors review the processes and physics that control precipitation phase as relevant to hydrologists, focusing on the importance of processes occurring aloft, and conclude that current PPMs are too simple to capture important processes and are not well validated for most locations.

TL;DR: In this paper, a detailed analysis is performed using rainfall observations and reanalysis circulation products to understand the evolution of monsoon-extratropical circulation features and their interactions based on 34 extreme precipitation events which occurred in the Western Himalayas (WEH) during the period 1979-2013.

TL;DR: In this article, a mesoscale numerical simulation of a well-observed gravity-wave event that occurred on 4 January 1994 along the East Coast of the United States is performed, showing clear evidence of strong imbalance associated with a middle-to-upper tropospheric jet streak, and tropopause fold upstream of the largeamplitude gravity wave several hours before the wave became apparent at the surface.
