  • [2/10/17] On Monday, we will start off class in the atrium by "Science On A Sphere" at 4 PM for our group photo with students and instructors. This is open to anyone involve in the class during the past few years, so spread the word to past students of this class!
  • [2/10/17] Bring all manual analysis materials to class next week -- charts from Steve Weiss, colored pencils, erasers, etc.
  • [2/16/17] Class on Monday, Feb. 20 will be in NWC 3910. We will have a change in the lecturer. Andrew Moore will be teaching on Monday, and you will receive Homework 1 and Quiz 2 back. There will be pizza..
  • [2/16/17] Wednesday's class with Rich Thompson will now be a hands-on forecast-practice class. To accommodate this adjustment, you are to watch ALL 5 of his videos related to supecells and tornadogenesis prior to class on Monday, Feb. 27. This is an assigned requirement.

  • [4/1/17] Class on Monday, 4/3, will extend until around 6:00 PM, though attendance after 5:15 PM is optional.s
  • [4/7/17] On Wednesday, April 12, student-teacher conferences will be held on the 2nd floor of the NWC. This will be our opportunity to exchange feedback on the course on a one-on-one basis. Come ready to discuss what participation score you think you have earned (out of 100 points), and how you can improve this score in the remaining weeks of class. Click here for the conference schedule.
  • [4/14/17] Wednesday of next week -- I have NWC 5600 reserved 6pm-9pm for us to practice the steps of analyzing surface and upper air charts. We can project observations to the board and then identify contours and boundaries. Food will be provided. Also, please let me know if there are any derivations you want to see again from earlier in the semester. While I realize they are recorded...if you want to see any with opportunities for questions, let me know and we can make some time. Also, we can talk about this more in class on Monday, but as far as an alternative time to the Final Exam -- I'm willing to consider an evening on Wednesday or Thursday during the week before Final Exams -- if we can get everyone together at the same time.
  • [5/2/17] Office hours today in the NWC atrium from 3:45 PM to 4:45 PM for the Final Exam.

    01/18/17 Homework 1 (Click Here) Due Monday, February 13, 2017 at the beginning of class. In Problem 1, I'm asking you to consider the differences between the convective environments influenced by positively tilted troughs versus negatively tilted troughs. When I use the word, "attendant," I'm referring to "associated with." Then when I use the word, "equivalent," I'm referring to -- all else the same. In other words, imagine leaving all mass-field-driven kinematic patterns and thermodynamic patterns identical between the two cases, just adjust the tilt of the trough, and what happens to the convective environment?
