Abstract: Eliassen-Palm cross sections and residual meridional circulations are presented for the Northern and Southern Hemispheres for summer and winter based on the data of Newell et al. (1972, 1974). The cross sections are similar ...

Abstract: The vacillatory behavior of the general circulation model described by Hunt (1978a,b) is analyzed using transformed Eulerian-mean diagnostics. This model was shown by Hunt to have large time variations in the troposphere ...

Abstract: Composite seasonal mean and anomaly fields prepared from operational numerical analyses have been used to describe the Southern Hemisphere (SH) circulation features associated with El Niño-Southern Oscillation (ENSO) events. ...

Abstract: Variations of Australian-average mean temperature and diurnal temperature range over the twentieth century are investigated. The observed interannual variability of both is simulated reasonably well by a number of climate ...

Abstract: Trends in surface temperature over the last 100, 50, and 30 yr at individual grid boxes in a 5° latitude?longitude grid are compared with model estimates of the natural internal variability of these trends and with the ...

Abstract: iurnal temperature range (DTR) is a useful index of climatic change in addition to mean temperature changes. Observational records indicate that DTR has decreased over the last 50 yr because of differential changes in ...

Abstract: Changes in the area of Australia experiencing concurrent temperature and rainfall extremes are investigated through the use of two combined indices. The indices describe variations between the fraction of land area ...

Abstract: Motivated by some results from barotropic models, a linearized steady-state five-layer baroclinic model is used to study the response of a spherical atmosphere to thermal and orographic forcing. At low levels the significant ...

Abstract: Several aspects of the precipitation climatology from the North American Regional Reanalysis (NARR) are analyzed and compared with two other reanalyses and one set of gridded observations over a domain encompassing the ...

Abstract: This note examines the sensitivity of simulated U.S. warm-season precipitation in the Weather Research and Forecasting model (WRF), used as a nested regional climate model, to variations in model setup. Numerous options ...
