REANALYSIS DATA DISCLAIMER
Please note that the plots found on this page use MODELED REANALYSIS data from the RAP/RUC (2005-present), ERA-5 (1958-present), and a preliminary back extension of the ERA-5 (1950-1978) – i.e. not actual observations of the atmosphere*. Because of this, the plots provided here may not be entirely representative of the actual atmosphere that existed at the time & location of these reanalyzed plots. However, these reanalysis data provide a vertical profile that should closely resemble that of the actual atmosphere at the time. Reanalysis data are subject to the parameterization and schemes of the respective model. Plot time and location for each plot are determined by the author in order to best reflect an accurate, uncontaminated, and as-representative-as-possible profile.
*A few cases in this library are actual RAOB profiles (marked RAOB) from NWS launch sites around the time of nearby tornado events.
Note that there have been no modifications to the raw model output. Some interpolation operations take place to simplify parameter calculation and data plotting. Parameter calculations are subject to the author’s discretion.
This archive is meant to act as a library of soundings that represent notable Michigan tornado environments in order to aid CMU student forecasters in tornadic-environment pattern recognition in the state of Michigan.
Important note: vertical profiles (soundings) are not the only data forecasters should use to analyze meteorological conditions and weather phenomena. Other data sources such as surface analysis, mesoanalysis, and upper-air data should be considered but are not provided here. Check out this page for additional archive data resources.
RAP model data comes from the NOAA NCAR THREDDS data server. ERA-5 data comes from the ECMWF CDS service. Tornado stat data comes from NOAA SPC / NCEI & NOAA NWS.

MICHIGAN TORNADO SOUNDING ARCHIVE GUIDE

ABOUT THESE PLOTS:
This plot style has been developed in a way that acts to provide as much information to the user as possible with attributes designed specifically for the analysis of severe convective environments. You will also find that this particular plot style lacks many of the common and popular severe weather composite indices – that was intentional. Most, if not all, of the data provided on this plot, are considered ‘true’ observations of the atmosphere and are not related to the ideology of ‘composite-index-forecasting’ but may be subject to heavy assumptions. The data on this plot are considered, by most, to be useful in determining critical characteristics of the atmosphere related to tornadogenesis. Additionally, analysis of the data presented is not provided here. This page is meant to act solely as a library of plots. However, in this section, you can find short descriptions of certain parameters and patterns to look for.
About the page author
This page, the plots in the archive, and the archive itself were created by Kyle Gillett, the webmaster for the CMU Student Chapter of the American Meteorological Society (2020-present). Kyle considers himself a very amateur programmer. He has also worked on other various projects such as MVP-RAP, the CMU Weather Mapwall, CMU Weather Model Viewer, maintaining this website, creating News Central graphic packages, and developing plots for Dr. Baxter’s electronic mapwall.
