The ability of forecasting systems to simulate tropical cyclones is still insufficient, and currently, there an increased interest in improving model performance for intense cyclones. In this study, the impact reducing surface drag at high wind speeds on modeling wave conditions during super Typhoon Lingling event over northwest Pacific Ocean 2019 investigated. response with respect parameteriz...

In decays of the Z, the dominant mechanism for the direct production of charmonium states is the decay of the Z into a charm quark or antiquark followed by its fragmentation into the charmonium state. We calculate the fragmentation functions describing the splitting of charm quarks into S-wave charmonium states to leading order in the QCD coupling constant. Leading logarithms of MZ/mc are summe...

We discuss a connection between axial anomaly and polarized radiative processes. By comparison with the corresponding unpolarized cases, we consider some physical outputs for the π+ and Z0 polarized radiative decays. We analyse in detail the pattern of mass singularity cancellation. PACS 11.30.Rd, 13.20.Cz, 11.15.Bt

We find pairs of solutions to a differential equation which is obtained as a special limit of a generalized spheroidal wave equation (this is also known as confluent Heun equation). One solution in each pair is given by a series of hypergeometric functions and converges for any finite value of the independent variable z, while the other is given by a series of modified Bessel functions and conv...

In recent years, several papers (for a complete reference list, see Chirka and Stout [3]) have been published on the subject of removable singularities for the boundary values of holomorphic functions on some domains or hypersurfaces in the complex euclidean space. In this paper, we study the higher codimensional case. Our results for the hypersurface case are weaker than those in [3] and [4], ...

Based on morphological methods, MODIS satellite remote sensing data were used to establish a dataset of the local roughness length (Z0) vegetation-covered surfaces in Guangdong Province. The Z0 was update mesoscale Weather Research and Forecasting (WRF) model order quantitatively evaluate its impact thermodynamic environment surfaces. specific results are as follows: evergreen broad-leaved fore...
