Abstract Accurate representation of cloud phase partitioning is critical for understanding the feedback to climate change, but supercooled liquid fraction often underestimated in global models, part due assumption homogeneous distributions hydrometeors mixed‐phase clouds. In this study, we take into account heterogeneous liquid‐ice mixing modeling ice depositional growth using airborne situ measurements. The impact on Wegener‐Bergeron‐Findeisen process parameterized as that mixed with water,...
Abstract Mixed‐phase stratiform clouds contain numerous liquid, mixed‐phase, and ice clusters, quantifying the cluster scales is potentially helpful to improve parameterizations of microphysics radiation models. However, hydrometeor clusters at different levels are not well understood. In this study, using airborne measurements a large eddy simulation, we show that turbulence plays an important role in controlling with length few hundred meters, while larger have stronger vertical variations...
Abstract. Ice microphysics controls cloud electrification in thunderstorms, and the various secondary ice production (SIP) processes are vital generating high concentrations. However, role of SIP cold-season thunderstorms is not well understood. In this study, impacts on a thunderstorm that occurred late November investigated using model simulations. The parameterizations four implemented model, including rime splintering, ice–ice collisional breakup, shattering freezing drops, sublimational...
Abstract In mixed‐phase cumulus clouds, droplets and ice crystals are inhomogeneously distributed, such spatial inhomogeneity can be enhanced by inhomogeneous entrainment as it strengthen the particle clustering, which may further influence phase partitioning interactions among hydrometeors. However, scale of clustering induced is not well known. Utilizing high‐resolution in‐situ aircraft measurements in this study shows due to entrainment‐mixing, cluster scales decrease approximately 10 m...
The distribution of ice particles strongly affects the microphysical processes in mixed-phase clouds, but inhomogeneity is not well understood. In this presentation and clustering a stratiform cloud system quantitatively analyzed using pair correlation function (PCF) method, based on airborne in-situ measurements from northeast China. results show that clusters scales few kilometers dominate distribution. Due to cumulative impact different scales, probability finding relative high...
Abstract As a key factor influencing the cloud life cycle and radiative properties, liquid‐ice mass partitioning remains major source of uncertainties in modeling mixed‐phase clouds. One unresolved problems is that mixing highly inhomogeneous, but it has not been well understood quantified for parameterization. In this study, homogeneity ( χ ) using information‐theoretic entropy based on airborne measurements. It demonstrated positively correlated with condensed water content (CWC). Cloud...

The COVID-19 pandemic is yet another reminder that the threat of infectious disease has never really gone away. As cornerstone preventing and controlling diseases, effective surveillance early warning are great significance in understanding outbreak epidemic specific diseases putting forward prevention control measures. Therefore, we must continue strengthening construction system. We reviewed practices major countries regions, then discussed development direction field to provide reference...

Methods: The weekly reported incidence rate (IR) percentage influenza-like illness (ILI%) 2011-2021 were collected establish models respectively. fitting effect two evaluated for purpose...
Objective: To explore the medical costs and influencing factors of patients diagnosed with Brucellosis in Datong Shanxi province. Methods: Information on demographics, visits, between January 1, 2017, December 31, 2019, were collected. Health care utilization analyzed from different genders, age groups, underlying diseases, clinical stages, comorbidities. Results: A total 2 289 (1 715 outpatient 574 inpatient cases) included analysis. 72.0% 649/2 289) male, an average (49.6±15.5) years;...
