Indications of thin cirrus clouds in the stratosphere at mid-latitudes
hin cirrus clouds stratosphere mid-latitudes
2009/2/19
This study is devoted to the possible presence of cirrus clouds in the stratosphere. Three months of lidar data collected in the south of France (44° N) for detection of stratospheric cirrus are caref...
Discriminating raining from non-raining clouds at mid-latitudes using multispectral satellite data
Discriminating raining non-raining clouds mid-latitudes multispectral satellite data
2009/1/16
We propose a new method for the delineation of precipitation using cloud properties derived from optical satellite data. This approach is not only sufficient for the detection of mainly convective pre...
Wind-profiler observations of gravity waves produced by convection at mid-latitudes
Wind-profiler observations gravity waves convection mid-latitudes
2009/1/13
This work presents a case study which includes regions of large rapidly varying vertical velocities observed by a VHF wind-profiler at Aberystwyth (52.4° N, 4.1° W). Analysis indicates that this regio...
Seasonal changes in gravity wave activity measured by lidars at mid-latitudes
Seasonal changes gravity wave activity mid-latitudes
2008/11/26
More than 230 nights of temperature measurements between 1 and 105 km have been performed at the Leibniz-Institute of Atmospheric Physics in Kühlungsborn with a combination of two different lidars, i....
First airborne water vapor lidar measurements in the tropical upper troposphere and mid-latitudes lower stratosphere: accuracy evaluation and intercomparisons with other instruments
airborne water vapor lidar troposphere mid-latitudes lower stratosphere intercomparisons
2008/11/19
In the tropics, deep convection is the major source of uncertainty in water vapor transport to the upper troposphere and into the stratosphere. Although accurate measurements in this region would be o...
Synoptic climate change as a driver of late Quaternary glaciations in the mid-latitudes of the Southern Hemisphere
synoptic climate change Quaternary glaciations mid-latitudes Southern Hemisphere
2008/11/10
The relative timing of late Quaternary glacial advances in mid-latitude (40-55° S) mountain belts of the Southern Hemisphere (SH) has become a critical focus in the debate on global climate teleconnec...
Discriminating raining from non-raining clouds at mid-latitudes using meteosat second generation daytime data
Discriminating raining from non-raining clouds at mid-latitudes using meteosat second generation daytime data
2008/11/6
A new method for the delineation of precipitation during daytime using multispectral satellite data is proposed. The approach is not only applicable to the detection of mainly convective precipitation...
Summertime stratospheric processes at northern mid-latitudes: comparisons between MANTRA balloon measurements and the Canadian Middle Atmosphere Model
northern mid-latitudes MANTRA balloon Canadian Middle Atmosphere Model
2008/11/4
In this paper we report on a study conducted using the Middle Atmospheric Nitrogen TRend Assessment (MANTRA) balloon measurements of stratospheric constituents and temperature and the Canadian Middle ...
Cirrus, contrails, and ice supersaturated regions in high pressure systems at northern mid latitudes
contrails ice supersaturated regions pressure system northern mid latitudes
2008/11/3
During the European heat wave summer 2003 with predominant high pressure conditions we performed a detailed study of upper tropospheric humidity and ice particles which yielded striking results concer...
