Determinants of fog and low stratus occurrence in continental central Europe – a quantitative satellite-based evaluation

, 2020
The formation and development of fog and low stratus clouds (FLS) depend on meteorological and land surface conditions and their interactions with each other.

Model For Estimating Vertical Extinction Profiles In Low Stratus Subclouds

SPIE Proceedings, 1988
A microphysical model is presented which can be used to provide first approximations of vertical extinction profiles for low stratus subclouds. The thermodynamic portion of the model is based on particle growth models by Hanel, drop-size distributions by Duncan and Low, or Shettle and Fenn, bulk phase change thermodynamics, and a mass balance ...

Low stratus at Embakasi Airport Nairobi

pure and applied geophysics, 1971
The relatively frequent occurrence of low cloud in the area of Embakasi Airport near Nairobi (Kenya) is a great hazard particularly to aircraft without automatic landing device. The desire was therefore that the flight direction and control staff receive early and reliable information of low cloud from the meteorologist. The great difficulty is evident

Forecasting Rain with Low Stratus in the Midlands of England

Bulletin of the American Meteorological Society, 1961
A semi-objective method of forecasting the onset of steady rain and associated low stratus, as well as the height of this stratus, is described and illustrated with selected cases. The procedures depend heavily on the proper interpretation of the 700-mb level, especially its wind and moisture fields.

Temperature and Moisture Gradients under Low Stratus Clouds*

Bulletin of the American Meteorological Society, 1952
The lapse rate of dew point is developed from thermodynamic relations. It is shown to have varied values depending on the flux of water vapor but to have a value of nearly 1.0F° per 1,000 feet for steady state. The lapse rate of temperature is developed after a method suggested by Priestley and Swinbank.

The Shipboard Use of a Low-Level Atmospheric Thermograph in Fog and Stratus Investigations

Journal of Applied Meteorology, 1980
Abstract A Low-Level Atmospheric Thermograph (LLAT) to obtain fine-scaled and detailed vertical temperature profiles to an altitude of 1000 m has been developed through a simple modification of the Sippican Expendable Bathythermograph (XBT) system. Only minutes are required for converting the system from one mode to the other, so taking atmospheric ...

Aircraft icing in visual meterological conditions below low stratus clouds

Atmospheric Research, 1995
Abstract There are many reports about icing slightly below stratus clouds in visual meteorological conditions (VMC), which obviously occurs very often but not only in polar regions and over the sea. Calculations of the ice shape at the leading edge of aircraft wings and the main rotor blades of helicopters by computers of GMGO (German Military ...

Fog and low-level stratus characteristics at the airport of Lviv from surface observations

2023
Fog and low-level stratus have been recognised as a hazardous weather phenomenon leading to several losses in time, money and even human life above all in aviation but also in other forms of transportation, such as navigation and land transportation. The forecast of low-level stratus and fog is one of the most difficult issues of aviation meteorology ...

Improved detection of low stratus and fog at dawn from dual geostationary (COMS and FY-2D) satellites

Remote Sensing of Environment, 2018
A novel method was proposed to detect low stratus and fog (LSF) at dawn during the summertime using near-simultaneous observations from dual geostationary-orbit satellites (GEOs): the Korean Communication, Ocean and Meteorological Satellite (COMS; 128.2 ...

Mesoscale data assimilation and prediction of low stratus in the Alpine region

Meteorology and Atmospheric Physics, 1997
A number of problems related to mesoscale numerical prediction of low stratus in the Alpine region are formulated, and addressed in a series of experiments for two wintertime cases. These problems include modelling aspects and issues of data assimilation which are relevant particularly in relation to the observation nudging technique. A focus is on the
