- It is found that the lightning can occur within the accumulated dust layer at ∼20–30 km altitudes.
- Abstract
- We have solved the Maxwellian equations of electromagnetic waves which oscillate within the cavity formed in the lower ionosphere of Mars between 0 and 70 km. The electrical conductivity and Schumann Resonance (SR) frequencies are calculated in the lower ionosphere of Mars, in the presence of a major dust storm that occurred in Martian Year (MY) 25 at low latitude region (25°–35°S). It is found that the atmospheric conductivity reduced by one to two orders of magnitude in the presence of a dust storm. It represents a small dust layer at about 25–30 km altitudes where lightning can occur. We also found that the SR frequencies peak at ∼18 km with values 19.9, 34.5 and 48.8 Hz for the modes l = 1, 2 and 3, respectively, in the non-homogeneous medium. Our results indicate that practical or measurable values of SR are dependent on the altitudes.
