The anomalous response of the tropical atmosphere to the recently discovered Indian Ocean Dipole has been studied in the present article, using an Atmospheric General Circulation Model (AGCM), and the NCEP/ NCAR Reanalysis. Our AGCM study shows that the response of the atmosphere to the IOD is of dipole-like pattern in the circulation, and is baroclinic. An anomalous circulation in the zonalvertical plane is induced, with the subsidence over colder pole and the upward motion over the warmer pole, modulating the Walker circulation over the equatorial Indian Ocean, as observed. An anomalous circulation in the meridional-vertical plane from the eastern pole of the dipole towards India, and the Bay of Bengal is simulated, which affects the Indian summer monsoon rainfall. The model atmosphere is heated by the anomalous surplus of the latent heat, the net long-wave radiation, and sensible heat fluxes over the warmer pole of the IOD. This results in an excess of net vertically integrated moisture convergence, and excess latent heat release in the atmospheric column above the warm pole. This energy, together with the anomalous convergence of enthalpy, is converted into anomalous mechanical energy and leads to the divergence of mechanical energy flux. This anomalous divergence of the mechanical energy in the upper tropospheric part of the column causes propagation of the disturbances to the surrounding regions. The mean seasonal circulation during the boreal summer is crucial for maintenance of the anomalous energy distribution and propagation during the IOD event. Transient high frequency variability does not appear to contribute much to the energy conversions.

“…Correlations between adjacent Umkehr layers were estimated by Klenk et al (1983) who found the correlation to neighbour layers to be 0.31-0.61 and to nextneighbour layers to be <±0.13. Their results are in general accordance to the values found here, but a direct comparison is di Y cult as the Umkehr layers represent a relative coarse vertical layering (average height # 4.5 km).…”

“…The statistical description of a stationary stochastic vector can be made by the type of probability distribution, the mean and the standard deviation of each element, and the correlation coe Y cients between di V erent elements. Zonal mean vertical pro les of both ozone (Klenk et al 1983, McPeters et al 1984, Keating et al 1996, Fortuin and Kelder 1998 and temperature (Oort 1983, Fleming et al 1990, Leblanc et al 1998 have been described while the other variables are less studied. The objective of this study is to provide probability density functions (PDFs), deviations between local means, and vertical correlation for ozone and temperature.…”

A reliable climatology of vertical ozone and temperature variability is essential for our understanding of climate, modelling work and pro le retrieval from passive remote sensing observations. This paper describes a statistical analysis of ozonesonde data collected from 1970 to 1996 at 17 stations in the northern hemisphere. The aim of the analysis is to provide a number of parameters describing vertical ozone and temperature variance, justi ed primarily by the importance of such information for remote sensing applications. Deviations between local means, probability density functions, standard deviations, and correlation between di V erent pressure levels are reported for altitudes below 10 hPa and three latitude bands (around 35°N, 50°N and 75°N). The analysis includes also cross-correlation between ozone and temperature. Di V erences are found between local mean values up to 40% and 15 K for ozone and temperature, respectively. Standard deviations are 10-80% for ozone and 2-15 K for temperature. For ozone the exponential correlation length is normally 2-5 km, while for temperature the vertical correlation is more inhomogenous. The implications for inversion of remote sensing measurements are discussed.

“…3.3 Diabatic heating Some thermal exciting forcing is needed to produce the basic mode of tonally symmetric diurnal tides. In this model the ozone density is tonally given from the climatological distribution of Klenk et al (1983). Thus diabatic heating due to the solar flux absorption by ozone can not have a significant diurnal variation in the zonal mean component.…”

Zonally Symmetric Diurnal Tides Simulated with a General Circulation Model

A large zonally symmetric diurnal variation is found in temperature and wind fields in a model general circulation of the middle atmosphere. This variation has a vertical wavelength of about 25 km and shows similar structures to those of the basic mode of zonally symmetric diurnal tides. The zonal component of diabatic heating projected to the horizontal structure function of this mode shows a prominent diurnal change with large amplitudes near the surface. The simulated zonally symmetric diurnal variation therefore is the basic mode of the upward propagating tides thermally excited in the lower troposphere, the amplitude of which mode becomes appreciably large in the middle atmosphere due to the density effect.
