============================================================================
I am a Professor in Atmospheric Sciences in the Department of Geosciences, Tel Aviv University. My main field of research deals with global lightning activity, and the connections between lightning activity and the Earth's climate. What determines the global distribution and frequency of lightning flashes? Will lightning activity change in a warmer climate? How do we measure global lightning activity from a single location on the earth's surface? Is lightning activity related to important climate parameters such as upper tropospheric water vapor and cirrus clouds? Does lightning have a significant impact on atmospheric chemistry? What are sprites, and can we study them from Israel? Do sprites exist on other planets? Is lightning activity related to flash floods, severe weather and perhaps hurricane generation and intensity? How important is lightning in causing forest fires? A lot of questions.....
I am also interested in other Atmospheric Electricity
problems and phenomenon. This involves carrying our field
measurements in the Negev Desert using sensitive equipment in different
frequency bands, from DC, to ULF, ELF and VLF. These data have
been used to study solar storms, the solar rotation, meteors, the
ionosphere, and even possible electromagnetic precursors before
earthquakes.
In addition to research, I
also
teach courses related to Atmospheric Physics, Climate Change, El Nino, Atmospheric Electricity,
Biomass Burning and Atmosperic Optics.
