1. The severe weather fronts is “projected” on ionosphere 120 km height
2. The delay of magnetic field response - 15-30 minutes (corresponded velocity 10-30 m / s)
3. «Projection» of weather fronts to North hemisphere!
Possible carrier? Atmosphere gravity waves AGW:
Severe troposphere weather front “pull” the AGW
Search of planetary wave propagation to ionosphere heights: E-layer (120 km)
LEMI-112a induction magnetometer
-ELF receiver: two orthogonal search-coil magnetometers
-frequency band 0,1 - 300 Hz
-low noise level – less than 0,03 pT/ at 10 Hz.
F2 layer height long-term changes :
+ - Faraday data, х – Vernadsky data
Greenhouse effect cooling in mesosphere (90 km),
“drop down” of ionosphere layers
in Vernadsky region and adjacent territory of Antarctic Peninsula
Other research: Geodesy survey,
GIS - GPS – gravimetric measurements
Permanent dual-frequency GPS receiver antenna installation at Vernadsky, Antarctica, April 2005
- tectonics
- total electron content
- troposphere humidity

After winter the Cs amount in body essentially decreased
Ukrainian winterers have usually increased amount of R/A Cs in body
Conclusion: Priorities of research
• Climate variability study ( ice cap )• Ozone hole (Oz and UV measurements)• Upper atmosphere – Space Weather
