| Observations of convective precipitation made with a portable X-band radar are compared to images retrieved from the Exeter C-band operational radar situated in southern Ontario during Elbow 2001: The Effect of Lake Breezes On Weather. Attempts were made with the X-band radar to locate and identify convective precursors of severe weather due to lake breeze boundary interactions. The boundary interactions on June 19th, July 4th, July 19th, and July 23rd of 2001, are presented as case studies to illustrate the performance strengths of each radar. As a diagnostic and prognostic observation and analysis tool, the X-band was able to make contributions to the research through its scanning flexibility. On July 19th, the X-band radar detected lower-level divergence coupled with upper-level convergence as a good example of downdrafts in the mature phase of a thunderstorm. On July 23rd, the X-band was used to make high-resolution scans of a downburst over St. Mary's, Ontario. In comparison, the more sensitive Exeter radar detected the boundary interactions that induced convective storms on June 19th, July 19 th and July 23rd. On July 4th, both radars were used to observe flow patterns in two storms approaching the Erie shore to determine the contribution of lake breezes to enhanced convection. |
