Impact of the East Asian summer monsoon on long-term variations in the acidity of summer precipitation in Central China
the East Asian summer monsoon long-term variations the acidity of summer precipitation Central China
2011/2/21
The acidity of precipitation has been observed at stations of the Acid Rain Monitoring Network run by the China Meteorological Administration (CMA-ARMN) since 1992. Previous studies have shown that di...

This report addresses the effects of pollution on the development of precipitation in clean ("pristine") and polluted ("hazy") environments in the Eastern Mediterranean by using the Integrated Communi...
Will climate change increase ozone depletion from low-energy-electron precipitation?
climate change ozone depletion low-energy-electron precipitation
2010/10/11
We investigate the effects of a strengthened stratospheric/mesospheric residual circulation on the transport of nitric oxide (NO) produced by energetic particle precipitation. During periods of high g...
Introducing the bromide/alkalinity ratio for a follow-up discussion on "Precipitation of salts in freezing seawater and ozone depletion events: a status report", by Morin et al., published in Atmos. Chem. Phys., 8, 7317–7324, 2008

Sander et al. (2006) proposed that CaCO3 precipitation can be an important factor in triggering tropospheric ozone depletion events. Recently, Morin et al. (2008b) presented calculations with the FREZ...
A feedback loop between regional scale deforestation and climate change was investigated in an experiment using novel, small size airborne platforms and instrument setups. Experiments were performed i...
Energetic particle precipitation in ECHAM5/MESSy1 – Part 1: Downward transport of upper atmospheric NOx produced by low energy electrons
ECHAM5/MESSy1 upper atmospheric NOx low energy electrons

precipitation chemistry wet deposition remote dry savanna site Africa
2009/3/13
Long-term precipitation chemistry have been recorded in the rural area of Banizoumbou (Niger), representative of a semi-arid savanna ecosystem. A total of 305 rainfall samples ~90% of the total annual...
Comparison of rain gauge observations with modeled precipitation over Cyprus using Contiguous Rain Area analysis
rain gauge observations modeled precipitation Cyprus Contiguous Rain Area
2009/2/16
Verification of modeled rainfall with precipitation observed by a rain gauge network has been performed in a case study over the Cyprus Island. Cyprus has a relatively dense rain gauge network. The ap...
The North Atlantic variability structure, storm tracks, and precipitation depending on the polar vortex strength
North Atlantic variability structure storm tracks polar vortex strength

Motivated by the strong evidence that the state of the northern hemisphere vortex in boreal winter influences tropospheric variability, teleconnection patterns over the North Atlantic are defined sepa...
Carbonate precipitation in brine – a potential trigger for tropospheric ozone depletion events
Carbonate precipitation potential trigger tropospheric ozone depletion events
2009/1/16
Tropospheric ozone depletion events (ODEs) at high latitudes were discovered 20 years ago and are attributed to bromine explosions. However, an unresolved issue is the explanation of how the acid-cata...
