Calgary Hail Project Research Meeting Notes
August 5, 2020
Attending: David Delene, Sankha Maitra, Andy Detwiler, Bruce Boe, Dan Gibert
Discussion
- Calgary 2017 has 25 - Analyzed Seed Case. 24 - Non-Analyzed (All seeded)
- Cases last 40-50 minutes of 45 Max dBz, 40 Minutes 15 - cases,50 Minutes 12 - Cases
- Case Environment There are so many parameters to look at for Hail.
- Software Repository.
Meeting next week, again Same time.
August 19, 2020
Attending: David Delene, Sankha Maitra, Andy Detwiler, Bruce Boe, Dan Gibert
Discussion
* Sankha show plots shear/cape plots for 2017. * Has all the text files, need to put in program. * CAPE, BRN, 0-4 shear. * Be care of what to use.
Task
- Sankha:
- AMS Abstract.
- Make environment plots that include Max Vil, average VIL.
- Get plots for all 2017 cases.
Meeting next week, again Same time.
August 26, 2020
Attending: David Delene, Sankha Maitra, Andy Detwiler, Bruce Boe, Dan Gibert
Discuss
- Sankha show three plots.
- Maybe use area under curve fit to VIL.
- Maybe average the rate of change VIL.
- Dan says Terry normalizes. Should try Terry method.
Tasks
- Sankha:
- Need more plots - Use Area.
Meeting next week, again Same time.
September 2, 2020
Attending: David Delene, Sankha Maitra, Andy Detwiler, Bruce Boe, Dan Gibert.
Discussion
- Calgary Issue - Reboot after meeting.
- Has two plots. Shear on X and Max VIL over Effective Seeding Period (20 Minute, till 20 minutes at end of seeding). Seed cases above 15.0 shear, Second plot - Average VIL for the Storm.
- 20 Days total for 2017.
Tasks
- KE Flux - Look and see if good estimating hail.
- Again check out what Terry did for normalization. Do similar analysis, create plot.
- Use Area > 60 dbz. Plot this.
Meeting next week, again Same time.
September 16, 2020
Attending: David Delene, Sankha Maitra, Dan Gibert.
Discussion
- Plot - Add labels.
- VIL Different between two values
Tasks to Adjust Plots
- Different colors for each ASP with line.
- Remove points 20 minutes after the end of seeding effect.
- Add trend line after effect of seeding starts.
- Add axis and title labels.
- Normalized
- Dan, normalize by middle point or points (2-3).
- Normalize by max over all VIL.
- Normalize by max before seeding effect.
- Max VIL at largest 60 dbZ size.
- Averaging
- Right now, just one point.
- Run average of 2-6.
- Difference before seeding effect and the points (1-6) after seeding effect
- Filter Data
- Above 30 VIL,
- Above 70 VIL,
- All data. Indicate this filter different on plot title.
Will be in my Zoom Room after 2 pm on Friday.

Discussion
- Plot Modifications
Meeting next week, again Same time.
September 30, 2020
Attending: David Delene, Sankha Maitra, Andy Detwiler, Bruce Boe, Dan Gibert (Not attending).
Discussion
- Looking at Plot - Change in VIL from two scans. Red is outside 100 km. This is just two points.
Tasks
- Split plot into 4 plots for each type.
- Look at second derivate for time.
- Average more than one data point.
- Compute some averages.
Meeting next week, again Same time.
October 14, 2020
Attending: David Delene, Sankha Maitra, Andy Detwiler, Bruce Boe (Not Attending), Dan Gibert
Discussion
- Plot of second derivative.
Tasks
- Sankha
- Program so points are correct.
- No line plots.
- Smooth out plots with average.
- Limit to 20 minutes after seeding for changes plots.
Meeting next week, again Same time.
October 21, 2020
Attending: David Delene, Sankha Maitra, Andy Detwiler, Bruce Boe (Not Attending), Dan Gibert
Discussion
- Interesting Plot - Need to calculate things using program, first derivate. Calculate the average and total number of points.
- Second plot, fix labels.
Tasks
- Sankha
- Fix plots, I'll work with you.
- Plot data with filter by wind shear.
Meeting next week, again Same time.
October 29, 2020
Attending: David Delene, Sankha Maitra, Andy Detwiler, Bruce Boe (Not Attending), Dan Gibert
Discussion
- 15 Case example. Some interesting.
- Fixed things in code.
Tasks
- Sankha - Do calculations for metrics.
- Sankha - Use an average.
Programming tomorrow and/or Friday.
Meeting next week, again same time.
November 4, 2020
Attending: David Delene, Sankha Maitra, Andy Detwiler, Bruce Boe (Not Attending), Dan Gibert
Discussion
- Couldn't get all plots. I can help.
- Discussed the plots. Need to keep making more plots.
- Need committee meeting this semester.
Meeting next week, again same time.
