Heterogeneous pyritaceous-polymetallic and copper-zinc-pyrrhotine deposits on the South slope of the Greater Caucasus are located in the Lower-Middle Jurassic terrigenous sediments. They were formed under a wide variation of physico-chemical parameters of mineral formation and are characterized by specific mineralogical-geochemical peculiarities. Ore-formation occurred in three stages. In the f...

In this study, the spatiotemporal distribution and characteristics of different precipitation types (stratiform, convective, snow) over China are analyzed using radar mosaic images during summer season 4 years (from 2018 to 2021). The convective occurs most frequently along eastern coast regions. June, strong convection center is located in Southern moves northward Eastern July, while lowest fr...

Public Key Infrastructure is a key infrastructure for secure and trusted communication on the Internet. This paper revisits the problem of providing timely certificate revocation focusing on the needs of mobile devices. We survey existing schemes then present a new approach where the principal’s server functions as the directory for its own revocation information. We evaluate the properties and...

A train of Kelvin–Helmholtz billows in a deep stratiform cloud over a mountain range is documented using data from a high-resolution vertically pointing airborne Doppler radar. The billows had a spacing of 2–2.5 km and a small aspect ratio. The formation and decay of the billows appear to be related to flow acceleration over a mountain.

The Goddard Convective-Stratiform Heating (CSH) algorithm has been used to retrieve latent heating (LH) associated with clouds and cloud systems in support of the Tropical Rainfall Measuring Mission (TRMM) Global Precipitation Measurement (GPM) mission. CSH requires use a cloud-resolving model (CRM) simulate LH profiles build look-up tables. This paper describes current V6 its differences/simil...

The potential of CloudSat W-band radar for observing wintertime storms affecting the West Coast of North America is evaluated. Storms having high hydrological impact often result from landfalls of ‘‘atmospheric rivers’’ (‘‘ARs’’), which are the narrow elongated regions of water vapor transport from the tropics. CloudSat measurements are used for retrievals of rain rate R and cloud ice water pat...

The evolution of the mesoscale flow and precipitation distribution are investigated for a small mesoscale convective system (MCS) that evolved in a nearly barotropic environment exhibiting moderate instability and weak wind shear. Observations primarily from a single Doppler radar detail the growth of the MCS from the merger of several clusters and lines of vigorous convective cells into a matu...
