Mesoscale Convective Complex (MCC) was first introduced in 1980 through research on infrared (IR) satellite images by Maddox. The MCC phenomenon can caused rain with a long period of time. This study aims to determine the atmospheric conditions when occurred East Kalimantan and surroundings area December 26, 2021. data used this is Himawari-8 display cloud top temperatures convective distributi...

The recent suggestion that lower-tropospheric cyclogenesis is predominantly a result of column stretching associated with the updraft portion of the shearwise quasigeostrophic (QG) vertical motion is quantified through direct calculation of 900-hPa height tendencies via the QG vorticity equation. Comparison of the separate lower-tropospheric height tendencies associated with the shearwise and t...

Reflectivities and Doppler velocities from an airborne 95 GHz radar are used to describe the detailed (~25 m) vertical structure of plumes and mesoscale convergence lines (‘fine-lines’) in the optically-clear convective boundary-layer (CBL). Multiple radar configurations are used, including a profiling mode, with fixed antennas looking up and down, and a vertical-plane dual-Doppler mode, employ...

From 1984 to 1986 tests were conducted to evaluate 4 trap types (ABADRL baffle trap, New Jersey trap, CDC trap, and updraft trap) with or without an incandescent light source, a suction fan or dry ice (as a source of CO2) for sampling adult Culicoides variipennis. The fewest flies were caught in the CDC and updraft traps. The New Jersey trap with suction, a strong light source and dry ice caugh...

Abstract. A hybrid bin microphysical scheme is developed in a parcel model framework to study how natural aerosol particles and different types of hygroscopic seeding materials affect the precipitation formation. novel parameter introduced describe impact on evolution drop size distribution. The results more than 100 numerical experiments using show that (a) Ostwald-ripening effect has substant...

The purpose of this study was to judge the feasibility of gasification for the disposal of waste streams generated through salmon harvesting. Gasification is the process of converting carbonaceous materials into combustible "syngas" in a high temperature (above 700 degrees C), oxygen deficient environment. Syngas can be combusted to generate power, which recycles energy from waste products. At ...

A mathematical model for studying the 3-D dynamical structure of lee wave across a meso-scale mountain corner has been proposed mean flow with realistic vertical variation wind and temperature. The basic consists both zonal component (U) meridional (V), which are assumed to be dependent height. Brunt-Vaisala frequency (N) is also This applied corner, in North East India, formed by broadly North...

Aitken mode particles are potentially an important source of cloud droplets in continental background areas. In order to find out which physico-chemical properties of Aitken mode particles are most important regarding their cloud-nucleating ability, we applied a global sensitivity method to an adiabatic air parcel model simulating the number of 5 cloud droplets formed on Aitken mode particles, ...
