Climatological features of blocking anticyclones: a study of Northern Hemisphere CCM1 model blocking events in present-day and double CO2 concentration atmospheres
Using output made with the National Center for Atmospheric Research (NCAR) Community Climate Model Version 1 (CCM1), the characteristics of blocking events over the Northern Hemisphere in a ten-year present day control simulation with a CO 2 concentration of 330 ppm were compared to those in a previously analyzed observational three-year climatology. The characteristics of blocking events in a ...
متن کاملA Climatology of Northern Hemisphere Blocking
In this paper a 55-yr (1948–2002) Northern Hemisphere blocking climatology is presented. Traditional blocking indices and methodologies are revised and a new blocking detection method is designed. This algorithm detects blocked flows and provides for a better characterization of blocking events with additional information on blocking parameters such as the location of the blocking center, the i...
متن کاملNorthern Hemisphere Summer Monsoon Singularities and Climatological Intraseasonal Oscillation
Using climatological pentad mean outgoing longwave radiation (OLR) and European Centre for MediumRange Weather Forecasts analysis winds, the authors show that the Northern Hemisphere summer monsoon displays statistically significant climatological intraseasonal oscillations (CISOs). The extreme phases of CISO characterize monsoon singularities—monsoon events that occur on a fixed pentad with us...
متن کاملNorthern Hemisphere atmospheric blocking as simulated
Northern Hemisphere atmospheric blocking as simulated by 15 atmospheric general circulation models in the period 1979–1988 Abstract As a part of the Atmospheric Model Inter-comparison Project (AMIP), the behaviour of 15 general circulation models has been analysed in order to diagnose and compare the ability of the different models in simulating Northern Hemisphere midlatitude atmospheric block...
متن کاملStationary planetary wave propagation in Northern Hemisphere winter – climatological analysis of the refractive index
The probability density on a height-meridional plane of negative refractive index squared f (nk<0) is introduced as a new analysis tool to investigate the climatology of the propagation conditions of stationary planetary waves based on NCEP/NCAR reanalysis data for 44 Northern Hemisphere boreal winters (1958–2002). This analysis addresses the control of the atmospheric state on planetary wave p...
