Modelling surface ozone during the 2003 heat-wave in the UK
surface ozone the 2003 heat-wave the UK
2010/9/1
The EMEP4UK modelling system is a high resolution (5×5 km2) application of the EMEP chemistry-transport model, designed for scientific and policy studies in the UK. We demonstrate the use and performa...
Planetary wave activity in the polar lower stratosphere
Planetary wave activity polar lower stratosphere
2010/2/1
Temperature data from the COSMIC GPS-RO satellite constellation are used to study the distribution and variability of planetary wave activity in the low to mid- stratosphere (15–40 km) of the Arctic a...
The two-day wave in the Antarctic and Arctic mesosphere and lower thermosphere
two-day wave Antarctic Arctic mesosphere lower thermosphere
2009/9/11
There have been comparatively few studies reported of the 2-day planetary wave in the middle atmosphere at polar latitudes. Here we report on a study made using high-latitude meteor radars at Rothera ...
Tropical cyclogenesis in a tropical wave critical layer: easterly waves
Tropical cyclogenesis tropical wave critical layer easterly waves
2009/8/7
The development of tropical depressions within tropical waves over the Atlantic and eastern Pacific is usually preceded by a "surface low along the wave" as if to suggest a hybrid wave-vortex structur...
Polar stratospheric clouds (PSCs) play a key role in polar ozone depletion. In the Arctic, PSCs can occur on the mesoscale due to orographically induced gravity waves. Here we present a detailed study...
Analysis of a jet stream induced gravity wave associated with an observed ice cloud over Greenland
jet stream gravity wave ice cloud Greenland
2009/3/3
A polar stratospheric ice cloud (PSC type II) was observed by airborne lidar above Greenland on 14 January 2000. It was the unique observation of an ice cloud over Greenland during the SOLVE/THESEO 20...
Evolution of stratospheric ozone during winter 2002/2003 as observed by a ground-based millimetre wave radiometer at Kiruna, Sweden
stratospheric ozone ground-based millimetre wave radiometer Kiruna
2009/2/10
We present ozone measurements from the millimetre wave radiometer installed at the Swedish Institute of Space Physics (Institutet för rymdfysik, IRF) in Kiruna (67.8° N, 20.4° E, 420 m asl). Near...
Analysis of the frequency-dependent response to wave forcing in the extratropics
frequency-dependent wave forcing extratropics
2009/1/15
A quasigeostrophic model for the frequency-dependent response of the zonal-mean flow to planetary-wave forcing at Northern Hemisphere (NH) midlatitudes is applied to 4-D-Var ECMWF analysis data for s...
Single particle analysis of ice crystal residuals observed in orographic wave clouds over Scandinavia during INTACC experiment
Single particle analysis of ice crystal orographic wave clouds Scandinavia INTACC experiment
2009/1/8
Individual ice crystal residual particles collected over Scandinavia during the INTACC (INTeraction of Aerosol and Cold Clouds) experiment in October 1999 were analyzed by Scanning Electron Microscopy...
Stationary planetary wave propagation in Northern Hemisphere winter – climatological analysis of the refractive index
Stationary planetary wave Northern Hemisphere winter climatological analysis refractive index
2008/11/27
The probability density on a height-meridional plane of negative refractive index squared f(nk2<0) is introduced as a new analysis tool to investigate the climatology of the propagation conditions of ...

Formation and transport of photooxidants over Europe during the July 2006 heat wave – observations and GEM-AQ model simulations
formation transport photooxidant heat wave observations GEM-AQ model
2008/10/29
The European heat wave of July 2006 was caused by advection of very hot and dry air from North Africa. Air masses were transported on the western edge of the high pressure system, centred over Eastern...

tropospheric wave tropical lower stratospheric water vapor
2008/10/28
Using water vapor data from HALOE and SAGE II, an anti-correlation between planetary wave driving (here expressed by the mid-latitude eddy heat flux at 50 hPa added from both hemispheres) and tropica...
