Principal Component Analysis Numerical Model Errors Analogue-dynamical Prediction
2011/8/16
Abstract: A new prediction error correction scheme based on 74 circulation characteristics data provided by Weather Diagnostic Forecasting Division of National Climate Center, which is designed to dev...
A few prospective ideas on climate reconstruction：from a statistical single proxy approach towards a multi-proxy and dynamical approach
climate reconstruction dynamical approach multi-proxy
2009/12/3
Important progresses have been made in palaeoclimatological studies by using statistical methods. But they are in somewhere limited as they take the present as an absolute reference. This is particula...
Dynamical implications of prescribing part of a coupled system:Results from a low-order model
Dynamical implications prescribing part coupled system low-order model
2009/11/13
It is a common procedure in climate modelling to specify dynamical system components from an external source; a prominent example is the forcing of an atmospheric model with observed sea surface tempe...
The role of boundary and initial conditions for dynamical seasonal predictability
role of boundary initial conditions dynamical seasonal predictability
2009/11/12
The importance of initial state and boundary forcing for atmospheric predictability is explored on global to regional spatial scales and on daily to seasonal time scales. A general circulation model i...
Dynamical modes associated with the Antarctic ozone hole
Dynamical modes Antarctic ozone hole
2009/8/7
Generalized Maximum Covariance Analysis (GMCA) has been developed and applied to diagnosing the dynamical modes associated with variations in the Antarctic spring ozone hole. GMCA is used to identify ...
Impact of large solar zenith angles on lower stratospheric dynamical and chemical processes in a coupled chemistry-climate model
large solar zenith angles lower stratospheric dynamical chemical processes coupled chemistry-climate model
2009/3/11
Actinic fluxes at large solar zenith angles (SZAs) are important for atmospheric chemistry, especially under twilight conditions in polar winter and spring. The results of a sensitivity experiment emp...
The roles of dynamical variability and aerosols in cirrus cloud formation
dynamical variability aerosols cirrus cloud formation
2009/3/11
The probability of occurrence of ice crystal number densities in young cirrus clouds is examined based on airborne measurements. The observations have been carried out at midlatitudes in both hemisphe...
Modelling atmospheric transport of α-hexachlorocyclohexane in the Northern Hemispherewith a 3-D dynamical model: DEHM-POP
α-hexachlorocyclohexane Northern Hemispherewith 3-D dynamical model DEHM-POP
2009/3/2
The Danish Eulerian Hemispheric Model (DEHM) is a 3-D dynamical atmospheric transport model originally developed to describe the atmospheric transport of sulphur into the Arctic. A new version of the ...
Switching cloud cover and dynamical regimes from open to closed Benard cells in response to the suppression of precipitation by aerosols
Switching cloud cover dynamical regimes closed Benard cells
2009/1/12
The dynamic structure of the weakly sheared atmospheric marine boundary layer (MBL) supports three distinct states of cloud cover, which are associated with the concentrations of cloud condensation nu...
Episode of unusual high solar ultraviolet radiation over central Europe due to dynamical reduced total ozone in May 2005
Episode of unusual high solar ultraviolet radiation central Europe dynamical reduced total ozone
2009/1/8
In late May 2005 unusual high levels of solar ultraviolet radiation were observed over central Europe. In Northern Germany the measured irradiance of erythemally effective radiation exceeded the clima...
The thermal and dynamical state of the atmosphere during polar mesosphere winter echoes
thermal and dynamical state atmosphere polar mesosphere winter echoes
2008/12/30
In January 2005, a total of 18 rockets were launched from the Andøya Rocket Range in Northern Norway (69° N) into strong VHF radar echoes called "Polar Mesosphere Winter Echoes" (PMWE). The ech...
