Dynamic and Thermal Processes in the Mid-Latitude Ionosphere over Kharkov, Ukraine (49.6° N, 36.3° E), During the 13–15 November 2012 Magnetic Storm: Calculation Results
- 80 Downloads
Calculation results of the variations of dynamic and thermal process parameters in geospace plasma during the 13–15 November 2012, magnetic storm (MS) over Kharkov are presented. The calculations were based on experimental data obtained on the Kharkov incoherent scatter radar, single in the European mid-latitudes. Calculations showed that during the MS there took place an increase, by modulus, of the values of vertical component of transfer velocity, due to ambipolar diffusion, up to a factor of 1.4–2.1. During the MS there took place a decrease of the values of energy input to the electron gas by about 20–35%. During the main phase of MS, the heat flux density transferred by electrons increased up to a factor of 2–2.5. Results of estimates of the zonal component electric field value Ey are presented. During the MS the value of Ey was −9.5 mV/m. The vertical component of plasma velocity due to electromagnetic drift vEB has been calculated.
