Correlation Coefficient Metric

(1/1)

RIKIAWS:
I was wondering if anyone could explain to me the metric "correlation coefficient" as it is used in determining when a funnel cloud becomes a tornado.  What I have read so far about this metric confuses me in how the metric is used.  My background is as a research psychologist and "correlation coefficient" is used very differently in the social sciences. 

I am continuing my search to learn more and I wanted to bounce this around in this forum to see if I could gain some additional insight to how it is used and if anyone has worked with data related to determining the thresholds with correlation coefficients.  I would be really interested in discussing this.

It doesn't. CC is used primarily as a tool to detect potential ground debris in the atmosphere by specific radar signatures. The only way I know that a funnel cloud has truly become a tornado, "officially", is seeing the condensation funnel visually touch the ground. Or, obviously, after the fact.

CC is used for more than ground debris, although that's one feature of CC - to differentiate between precipitation and ground debris. NWS has a good, short, training on CC here: https://training.weather.gov/wdtd/courses/rac/products/cc/story_html5.html

Thank you, I will take a look.
