Solar Influence

This chapter discusses how measurements made over several decades from meteorological balloons across the globe were used to study variations in the average temperature of the atmosphere up to the lower stratosphere. Correlations between this temperature and solar activity, usually indicated by the solar 10.7 cm radio wave flux, were estimated, and a strong relationship was identified in mid-latitudes, implying temperature differences in that region of up to 1 K between minimum and maximum of the 11-year solar cycle. Continued observations, including from space-borne instruments, confirmed this signal over subsequent solar cycles. Subsequent work in this area sought to isolate the solar effect from other possible influencing factors using multiple linear regression analysis.

Longwave Flux

An attempt has been made to estimate longwave radiative flux from sea surface using semi empirical models with the help of routinely observed meteorological parameters during the monsoon season. The estimated values are then compared with observed values to find out an appropriate method to compute a longwave flux.       The study shows that clouds play an important role in determining the longwave flux. It IS found that lack of detailed knowledge of clouds obtained from ground based observations is responsible for the errors in the estimation of longwave flux. The errors are reduced using a regression method based on Monsoon-77 data set. The method was then tested with Monex-79 data set which served as independent data set. The method thus developed considerably reduces the errors associated with the estimation of long wave flux.

Dynamic Phenomena

It is well-known that solar activity is basically caused by the Interaction of magnetic fields with convection and solar rotation, resulting in a great variety of dynamic phenomena, like flares, surges, sunspots, prominences, etc. Many conferences have been devoted to solar activity, including the role of magnetic fields. Similar attention has not been paid to the role of magnetic fields for the overall dynamics and energy balance of the solar atmosphere, related to the general problem of chromospheric and coronal heating. To penetrate this problem we have to focus our attention more on the physical conditions in the ‘quiet’ regions than on the conspicuous phenomena in active regions.

The following subjects were discussed:(1)Filament activation(2)Post-flare loops.(3)Surges and sprays.(4)Coronal transients.(5)Disk vs. limb observations.(6)Solar cycle variations of prominence occurrence.(7)Active prominences patrol service.Of all these items, (1) and (2) were discussed in most detail and we also pay most attention to them in this report. Items (3) and (4) did not bring anything new when compared with the earlier invited presentations given by RUST and ZIRIN and therefore, we omit them.
