Presentation Transcript

  1. Topics • Lightning and Climate Change • lightning as a global thermometer • Brief E&M review (Gauss’s Law) • The DC global circuit, Carnegie curve, origin and behavior of the fair weather electric field • Thunderstorms • Charge structures • Charging theories, non-inductive (and inductive) • Involving mixed phase microphysics

  2. Continued… • Lightning mapping and detection • Northeast Colorado Lightning Mapping Array • Geostationary Lightning Mapper; LIS on ISS • Transient Luminous Events • Sprites, elves, jets • The CAPE vs. aerosol debate for convective invigoration and lightning production • Lightning in tropical Lightning detection by radar

  3. Continued… • Lightning and severe storms; lightning jump algorithm • Lightning in relation to rainfall and other storm properties. Combining lightning and IR to improve convective rainfall estimation via geostationary satellite • We will use some of the recent AGU Franklin lectures to motivate some of our discussion section (Earle Williams; Lightning and Climate and Davis Sentmann; Transient Luminous Events)

  4. Class procedure • Each student will give several in class presentations (review assigned papers). • We will follow a particular theme for 2-3 class periods • Grading based on in class presentations, participation in discussion and a final paper • Final paper—topic of your choice that was covered in class
