A statistically predictive model for future monsoon failure in IndiaSchewe J. - IOPscience, 2012Indian summer monsoon (ISM) rainfall is the major prerequisite of agricultural productivity in the region and its variability severely affects the livelihoods of a large share of the world’s population. While average ISM rainfall has been relatively stable during the past century, rising trends have been observed in the annual number of extreme rain events. This study shows severe failure of ISM rainfall is possible but unlikely under present climatic conditions, according to a comprehensive climate model. However, monsoon failure is projected to become much more frequent over the next 200 yea ...

Indian summer monsoon (ISM) rainfall is the major prerequisite of agricultural productivity in the region and its variability severely affects the livelihoods of a large share of the world’s population. While average ISM rainfall has been relatively stable during the past century, rising trends have been observed in the annual number of extreme rain events. This study shows severe failure of ISM rainfall is possible but unlikely under present climatic conditions, according to a comprehensive climate model. However, monsoon failure is projected to become much more frequent over the next 200 years as a result of global warming. The climate model presented in the paper provides a simple dynamical explanation for future changes in the frequency distribution of seasonal mean all-Indian rainfall. The approach offers an alternative perspective on large-scale monsoon variability as the result of internal instabilities modulated by pre-seasonal ambient climate conditions.

JCOMM Technical Report, 68. 8th JCOMM-TCP Workshop on Storm Surge and Wave Forecasting (SSW-8): proceedingsThe Eighth JCOMM-TCP Workshop on Storm Surge and Wave Forecasting (SSW-8) was held at the Institute for Meteorological Training and Research (IMTR), Nairobi, Kenya, from 19 to 23 November 2012.
This series of workshop is co-organized by the Joint WMO-IOC Technical Commission for Oceanography and Marine Meteorology (JCOMM) and the WMO Tropical Cyclone Programme (TCP), with a view to enhancing capacities of the National Hydrological and Meteorological Services (NMHSs) in providing necessary forecasting and warning services against natural marine hazards that complement b ...

Dependence of the single-scattering properties of small ice crystals on idealized shape modelsAtmospheric Chemistry and Physics (ACP), Vol. 11. N° 7. Um J.; McFarquhar G.M. - Copernicus GmbH, 2011The projections of small ice crystals (with maximum dimension <50 μm) appear quasi-circular when imaged by probes on aircraft flying through cloud. Therefore, idealized models constructed to calculate their single-scattering properties have included quasi-spherical models such as Chebyshev particles, Gaussian random spheres, and droxtals. Recently, an ice analogue grown from sodium fluorosilicate solution on a glass substrate, with several columns emanating from a common center of mass, was shown to be quasi-circular when imaged by state-of-the-art cloud probes. In this study, a new idealized ...
Multi-scale modeling study of the source contributions to near-surface ozone and sulfur oxides levels over California during the ARCTAS-CARB periodAtmospheric Chemistry and Physics (ACP), Vol. 11. N° 7. Huang M.; Carmichael Gregory R.; Spak S.N.; et al. - Copernicus GmbH, 2011Chronic high surface ozone (O3) levels and the increasing sulfur oxides (SOx = SO2+SO4) ambient concentrations over South Coast (SC) and other areas of California (CA) are affected by both local emissions and long-range transport. In this paper, multi-scale tracer, full-chemistry and adjoint simulations using the STEM atmospheric chemistry model are conducted to assess the contribution of local emission sourcesto SC O3 and to evaluate the impacts of transported sulfur and local emissions on the SC sulfur budgetduring the ARCTAS-CARB experiment period in 2008. Sensitivity simulations quantify c ...
Saharan and Asian dust: similarities and differences determined by CALIPSO, AERONET, and a coupled climate-aerosol microphysical modelAtmospheric Chemistry and Physics (ACP), Vol. 11. N° 7. Su L.; Toon O.B. - Copernicus GmbH, 2011This study compares the properties of atmospheric dust from the Saharan deserts and the Asian deserts using data from CALIPSO and AERONET during 2006 and 2007 along with simulations using a coupled climate-microphysical sectional model. Saharan deserts are largely south of 30° N, while Asian ones are primarily north of 30° N, hence they experience different meteorological regimes. Saharan dust lifting occurs all year long, primarily due to subtropical weather systems. However, Asian dust is lifted mostly in spring when mid-latitude frontal systems lead to high winds. Rainfall is more abundant ...
Evaluating a 3-D transport model of atmospheric CO2 using ground-based, aircraft, and space-borne dataAtmospheric Chemistry and Physics (ACP), Vol. 11. N° 3. Feng L.; Palmer P.I.; Yang Y.; et al. - Copernicus GmbH, 2011We evaluate the GEOS-Chem atmospheric transport model (v8-02-01) of CO2 over 2003–2006, driven by GEOS-4 and GEOS-5 meteorology from the NASA Goddard Global Modeling and Assimilation Office, using surface, aircraft and space-borne concentration measurements of CO2. We use an established ensemble Kalman Filter to estimate a posteriori biospheric+biomass burning (BS + BB) and oceanic (OC) CO2 fluxes from 22 geographical regions, following the TransCom-3 protocol, using boundary layer CO2 data from a subset of GLOBALVIEW surface sites. Global annual net BS + BB + OC CO2 fluxes over 2004–2006 for ...
Sensitivity of mesoscale model urban boundary layer meteorology to the scale of urban representationAtmospheric Chemistry and Physics (ACP), Vol. 11. N° 3. Flagg D.D.; Taylor P.A. - Copernicus GmbH, 2011Mesoscale modeling of the urban boundary layer requires careful parameterization of the surface due to its heterogeneous morphology. Model estimated meteorological quantities, including the surface energy budget and canopy layer variables, will respond accordingly to the scale of representation. This study examines the sensitivity of the surface energy balance, canopy layer and boundary layer meteorology to the scale of urban surface representation in a real urban area (Detroit-Windsor (USA-Canada)) during several dry, cloud-free summer periods. The model used is the Weather Research and Forec ...
Representation of tropical deep convection in atmospheric models – Part 1: Meteorology and comparison with satellite observationsAtmospheric Chemistry and Physics (ACP), Vol. 11. N° 3. Russo M.R.; Marécal V.; Hoyle C.R.; et al. - Copernicus GmbH, 2011Fast convective transport in the tropics can efficiently redistribute water vapour and pollutants up to the upper troposphere. In this study we compare tropical convection characteristics for the year 2005 in a range of atmospheric models, including numerical weather prediction (NWP) models, chemistry transport models (CTMs), and chemistry-climate models (CCMs). The model runs have been performed within the framework of the SCOUT-O3 (Stratospheric-Climate Links with Emphasis on the Upper Troposphere and Lower Stratosphere) project. The characteristics of tropical convection, such as seasonal c ...
CAWCR technical report, 39. Assessment of international seasonal rainfall forecasts for Australia and the benefit of multi-model ensembles for improving reliabilityIn this report we assess forecasts from Predictive Ocean Atmosphere Model for Australia (POAMA) in comparison to international dynamical coupled model forecast systems, which are archived as part of the ENSEMBLES project. We investigate how universal the lack of reliability is in dynamical forecasts of regional rainfall, in order to highlight any potential for improvement of the POAMA system. The systems assessed in this report show that overconfidence and lack of reliability for regional rainfall forecasts is a common problem. Due to the clear need for improved reliability and more accurate s ...
