Atmospheric Visibility and Meteorological Characteristics of the Upper Troposphere over Selected Cities in NigeriaAtmospheric visibility usually demonstrates some distinctive local or regional features since it is influenced by both air pollutants and meteorological parameters [7-10]. The reduction of ...
The perturbation to the zonal wind component is characterized by an out-of-phase behaviour between the lower and upper troposphere which is most coherent in the convective regions of the Indian Ocean and West Pacific. The stream-function anomalies in these regions are suggestive of a coupled ...

North of 80°N and near the surface, the mean Arctic age of air is about 1 week in winter and 2 weeks in summer. It decreases rapidly with altitude to about 3 days in the upper troposphere. In the most isolated regions of the Arctic, air is exposed to continuous darkness for, on ...
daily-mean reanalysis data (1975-2005), it is found that the upper troposphere anti-cyclone to the east of the Philippines break into two portions, the west anticyclone is above the Indo-China Peninsula (ICP) while the east one still stays above the ocean to the east of the Philippines. ...
the presence of the temperature inversion layer.The inversion layer with high humidity in lower atmosphere often associated with freezing rain.(2) Formation of freezing rain needed to meet three main conditions: freeze layer existed in the upper troposphere,a warm layer and temperature inversion ...
The energy dispersion feature of the Rossby wave in association with the summertime persistent anomaly events of mid-and high-latitude Eurasia is investigated in terms of the westerly waveguide structure and a wave-activity flux.In the upper troposphere,there is a weak waveguide with a complicated...
The temporal consistency of temperature analysis has also been considerably improved compared to previous reanalysis products. Our initial quality evaluation revealed problems such as a warm bias in the upper troposphere, large upward imbalance in the global mean net energy fluxes at the top of the ...
Lidar Measurements of Cloud and Aerosol in the Upper Troposphere in Beijing北京地区对流层中上部云和气溶胶的激光雷达探测 A new multi-wavelength lidar is introduced. The characteristics of 532 nm extinction coefficient profiles of cloud and aerosol in the upper troposphere in ... Qiu Jinhuan,Zheng Si...
A closed low-level atmospheric circulation, strong winds, and a spiral arrangement of thunderstorms with heavy rains are the critical characteristics of TC. Sufficiently warm sea surface temperature (SST) (> 26 °C), Coriolis force, vorticity in the low-level troposphere, relative humidity, ...
