Mesoscale Numerical Simulation and Cloud Microphysical Characteristics of the Warm Zone Blizzard in Northern Xinjiang
Published 2024-02-01“…The warm zone blizzard are both infrequent and highly destructive, making their accurate prediction a challenging and crucial focus.This study utilized four distinct cloud microphysics schemes (Lin, Thompson, WDM6, and WSM6) within the WRF mesoscale model to conduct a numerical simulation of a typical warm zone blizzard process in the northern Xinjiang in the middle of November 2016.The research objectives encompassed the evaluation of the model's capacity to simulate the warm zone blizzard, the selection of an optimal parameterization scheme, an analysis of the vertical distribution and evolution of hydrometeors during the snowstorm, and an exploration of the developmental patterns of related mesoscale systems contributing to the snowstorm.The analysis yielded the following key findings: (1) Among the diverse cloud microphysics parameterization schemes tested, the Lin scheme demonstrated the most favorable performance, effectively simulating snowfall magnitudes, spatial distributions, and trends.(2) In the cloud, all kinds of water condensate particles are active in the lower and middle troposphere, with graupel and snow being the most.Ice crystals, snow, cloud water and graupel particles are distributed from the upper layer to the lower layer.Near the windward slope of Altai Mountain is the center of the large concentration of each water condensate particle.The vertical alignment of the high value center of the four kinds of cloud water condensate particles in the strong snowfall area is conducive to the transformation of each particle.(3) High-humidity systems upstream moved westward, with the intensification of low-level southward jet streams resulting in pronounced moisture convergence.The western foothills of the Altai Mountains acted as a barrier, promoting moisture convergence by blocking the windward side; The low-level southerly jet also provides a continuous updraft and unstable condition for the generation of the blizzard.Strong snowfall is located in a wide updraft area between two groups of secondary circulations.The explosive growth of vertical movement is conducive to triggering the release of unstable energy, providing strong dynamic lifting conditions for the development and maintenance of the blizzard.…”
