1 Tropical Channel Model

Numerical models are primary tools used for weather forecast and climate projections. Richardson (1922) made the first effort to predict weather numerically. Subsequently, a number of simple

MJO and its relationship to ENSO

[1] In this study, we detected the spatial and temporal characteristics of Madden-Julian Oscillation (MJO) using zonal winds at the surface and outgoing long-wave radiation (OLR) from the NCEP-NCAR

The Characteristics of the Change of Hadley Circulation during the Late 20th Century in the Current AOGCMs

The changes in the Hadley circulation during the second half of the 20th century were examined using observations and the 20C3M (Twentieth Century Climate in Coupled Models) simulations by the 21

Climatological Vertical Features of Hadley Circulation Depicted by the NCEP/NCAR, ERA40, NCEP-DOE, JRA25, ERA-Interim, and CFSR Reanalyses

The climatological features of the pole-ward, equator-ward edges, and the width of the tropical Hadley Cell (HC) during the annual cycle in each hemisphere are studied based on six reanalyses

The Growth and Triggering Mechanisms of the PNA : A MJO-PNA Coherence

A prominent mode of low-frequency variability in the northern extratropical winter known as the Pacific/North American (PNA) teleconnection pattern prevails not only on seasonal but also on

Climatology of Tibetan Plateau vortices derived from multiple reanalysis datasets

The Tibetan Plateau vortex (TPV) is a mesoscale weather system active in the near-surface layer, which is one of the major systems for the generation of precipitation in the Tibetan Plateau (TP).

Modulation of the Period of the Quasi-Biennial Oscillation by the Solar Cycle

The authors examine the mechanism of solar cycle modulation of the Quasi-Biennial Oscillation (QBO) period using the Two-and-a-Half-Dimensional Interactive Isentropic Research (THINAIR) model.



Can climate trends be calculated from reanalysis data

Several global quantities are computed from the ERA40 reanalysis for the period 1958-2001 and explored for trends. These are discussed in the context of changes to the global observing system.

On the (In)Homogeneity of Reanalysis Products

Abstract The homogeneity of the ECMWF 40-yr Re-Analysis (ERA-40) is assessed. This is done by comparing ERA-40 data with results from the NCEP–NCAR reanalysis and also by investigating a known

Climate and surface mass balance of the polar ice sheets in ERA 40 / ERA 15

The density of meteorological observations in the polar regions, including the polar ice sheets, is comparatively low. There is thus great hope that, by making optimized use of the few available

Strong Trends in the Skill of the ERA-40 and NCEP–NCAR Reanalyses in the High and Midlatitudes of the Southern Hemisphere, 1958–2001*

Abstract The European Centre for Medium-Range Weather Forecasts (ECMWF) Re-Analysis (ERA-40) and the National Centers for Environmental Prediction–National Center for Atmospheric Research (NCEP–NCAR)

A case study of excessive subtropical transport in the stratosphere of a data assimilation system

[1] Assessments of transport show that results derived from assimilated (or analyzed) winds exhibit significantly larger mixing and entrainment rates compared to those derived from general

An Evaluation and Intercomparison of Global Analyses from the National Meteorological Center and the European Centre for Medium Range Weather Forecasts

In order to help establish a global climate record data sets of global analyses from the U.S. National Meteorological Center (NMC) and the European Centre for Medium Range Weather Forecasts (ECMWF)

ERA-40 representation of the arctic atmospheric moisture budget

The European Centre for Medium-Range Weather Forecasts (ECMWF) 40-year Reanalysis (ERA-40, 1957present, Uppala et al. 1999) has been eagerly awaited by the scientific community. It is a valuable

Use of Reduced Gaussian Grids in Spectral Models

Abstract Integrations of spectral models are presented in which the “Gaussian” grid of points at which the nonlinear terms are evaluated is reduced as the poles are approached. A maximum saving in

A new perspective on southern hemisphere storm tracks

Abstract A detailed view of Southern Hemisphere storm tracks is obtained based on the application of filtered variance and modern feature-tracking techniques to a wide range of 45-yr European Centre

Numerical forecasts of stratospheric warming events using a model with a hybrid vertical coordinate

A numerical forecast model based on use of a hybrid vertical coordinate which is terrain-following at low levels but which tends continuously to a pressure coordinate at upper levels is introduced.
