Investigations of solar-atmospheric effects with periods different from proper periods of interaction in the atmospheric-oceanic system are of great scientific and practical interest. The frequency structure of the interaction between the solar activity (represented by Wolf numbers), geomagnetic activity (represented by the aa-index) and mean square troposphere temperature anomalies is analyzed in this work. The temperature data for 65o, 40o and 20o latitudes separately for January and July were used to carry out the mutual spectral analysis. The periods are investigated over the 2-30 year interval.

The analysis of coherence between temperature anomalies and Wolf numbers shows a significant maximum in the coherence spectrum for the period 11 years in January at 65o latitude and a weakening of the tightness of the connection toward the lower latitudes. The connection between temperature anomalies and aa-index reveals the typical 22-year maximum in the coherence spectrum.

The frequency structure of the connection between the Wolf numbers, the aa-index, and the multiyear changes of zonal and meridional tropospheric temperature gradients is also considered for January, April, July and October. The results reveal a complex structure of the connection with the main solar cycle manifestation in January and weakening of the tightness of the connection in October.

During October 1988 - March 1989 at Heiss Island (80N, 58E) were made simultaneous measurements of the stratospheric ozone and temperature at the polar night.To study of structure and dynamics of the ozone layer was used the ground-based mm-wave instrument. The instrument was consisted of a millimeter wave receiver and multichannel spectrometer. The receiver was tuned to observe the rotational transition of ozone at 101.737 GHz. The uncooled receiver had a single sideband noise temperature of 5000oK. The filter bank spectrometer was covered 102 MHz with 20 filter channels which corresponded an altitude range of 22 to 52 km. The measurements of atmospheric emission spectra ozone were realized by the method of zenith-angle variations. The altitude profiles of the ozone concentration were computed for each spectrum by a model-fitting method. The pressure and temperature profiles used here were taken from balloon and rocket sounding data.

The temperature and pressure profiles above 25 km up to 70 km were derived both by rocketsondes every one week (sometimes every 3 days) and meteorological soundings (below 25 km) i.e. radiosondes flights being made three times daily.

During October-December, when Heiss Island located inside of upper level vortex, was remarked the general decrease of the stratosphere temperature. It is intresting to note that while in the 20-30 km layer is observated a step growth of ozone concentration, above 30 km appeared high correlation between the variations of the ozone and temperature in this time. On the first decade of February vortex disturbance was beginning with strong stratospheric warming. During the three weeks "the warm" descended from stratopause level (50 km) to lower stratosphere. The most heat is observated in the 18-30 km layer (60 deg and more). During this period the ozone concentration increased by 2-4 times at all sounding range. Following cooling of stratosphere by 20 deg caused ozone decrease by 1.5 times and formation of minimum on the end of February and the beginning of March 1989.

Spatial distribution of vertical energy flux in the mountain lee, caused by IGW generation over Scandinavian's mountain chain. Theoretical mechanism of IGW generation by choppy winds and empirical regularity, obtained by spectrophotometric measurements, are used. Amplitude of energy influx directly proportional to wind velocity, blowing on mountain chain at tropospheric heights (about 3-4 km). Disturbance in the mesopause displais by the increasing of temperature at 90 km about 10 K. The north part of Scandinavian's mountain chain is in auroral oval. Therefore, the effects in characteristics of aurora and accompanying processes, correlated with parameters of wind regime over montain chain, namely, connected with temperature variations of neutral atmosphere and its vertical shift up to several kilometers, evidently must to observe.

Bright multicolor clouds were observed at Kola peninsula during 16-23 January 1997 after a rocket launch. They were registered in Apatity, Murmansk and Lovozero by photocameras, TV camera and spectroscope. They were seen well as in twilight and dawn as in noon with the Sun elevation +2 deg. Their height is appreciated as 12 km according the time of disappearance in the shadow. Despite the big wind velocity in stratosphere about 35 m/s, the clouds did not moved practically. The meteorological situation was analyzed on the basis of Murmansk Hydrometeorological Centre data. The celling structure of the clouds was observed. We suppose that colour features are the result of scattering of the solar radiation on small particles of exhausted products involved into specific meteorological situation.

The changes of night-mean temperature at 87 km are obtained from the hydroxyl emission measurements data during international programm CRISTA-MAHRSI (October-December 1994). The empirical model of hydroxyl emission allowed to calculate the expected variations during this period. The comparison measured and model results revealed temperature variations of planetary scale with a period of 15-16 days caused by planetary waves. The amplitude of these waves at 87 km is about 10 K and the waves take place up to high latitudes. It is likely that auroral zone to respond to the dynamic of the mentioned time scale.

The way to obtain an information on the response of human cardiac system to the geophysical disturbances is to carry out real time measurements of cardiorhythm parameters and variation of geophysical fields. The cardiac rhythmology method proposed by prof. Victor Baevsky was used in the original sensor and software system made in the Polar Geophysical Institute. This method and equipment were tested in cardiac department of the Hospital of the Kola Science Center (Drs. Lyudmila Porina and Tatyana Galtsova) and gave some positive results. Some investigations by the method were carried out in the Murmansk Military Hospital (Drs. Lev Sokol and Alexander Fisher). Both the healthy and sick people in the North react to geomagnetic disturbances and it is possible to registrate by abovementioned method. In the disturbanced days some parameters which supposedly characterized adaptation function of human organism to external effects are rise. There are amplitude of mode and index of stress. But variation of amplitude (the difference between maximal and minimal values of cardiac intervals) is depressed. Those previous data point out to validity of the method for studies of influence of geomagnetic activity on a human cardiac system. We have a good possibilities to continue this kind investigation at Kola Peninsula where both geophysical observatories and medicine clinics situated in the same places and are opened for collaboration.
