The interaction of a frontal system with the extreme orography of the Andes mountain range is examined for a case of intense precipitation in central Chile during June 2002. The heavy rainfall was associated with a synoptic scale rainband that moved slowly over central Chile during a 48 hour period. Numerical simulations with the WRF mesoscale model show that both the intensification of precipi...

How global precipitation will change in the future is of great socio-economic importance. It is therefore vital that climate models are able to adequately simulate the characteristics of precipitation and the individual precipitation events. Fronts play an important role in providing precipitation and they can be associated with heavy rain and flooding. In this paper the ACCESS1.3 atmosphere mo...

1 N umerous papers have documented an increase in extreme precipitation events in the US over the past 30 years or so. The fundamental cause of this trend is a subject of active research. The purpose of this study is to examine the meteorological factors that underlie the trend, specifically to determine the contributions of the major types of meteorological precipitation-producing systems to t...

This study is devoted to the evaluation of the role of assimilation of conventional data on the quantitative precipitation forecasts at regional scale. The conventional data included surface station reports as well as upper air observations. The analysis was based on the simulation of 15 cases of heavy precipitation that occurred in the Eastern Mediterranean. The verification procedure revealed...

[1] Fluvial deposits in a basin north of Holden crater exhibiting a sinuous, anabranching pattern are of deltaic or fan origin. Channel width and meander wavelength indicate persistent flow magnitudes of about 700 m/s. If these flows were produced by quasi-periodic climate episodes involving typical terrestrial-style precipitation, the deposit required thousands to millions of years to accumula...
