A particularly valuable service is our StormProperties analysis. Using our data archive and StormData data quality management processes, OneRain has developed a technique to accurately characterize real-world storms that have been experienced since the inception of NEXRAD radar. StormProperties analyses enable our clients with critical, rainfall-dependent missions to track real storm behaviors that must affect their future planning.
Rainfall properties derived using StormProperties include depth area reduction factors (DARFs), spatial intensity distribution, statistical properties of storm cells with respect to their size, speed and direction, births and deaths of storms, orographic effects, seasonal changes in behavior, and more. The underlying TITAN statistics in which StormProperties is grounded can be used to calculate and characterize many attributes of value to a variety of uses.
Realistic Design Storms
A primary use of StormProperties is to create realistic design storms, in which the changes in intensity and the spatiotemporal distribution of rainfall used for modeling runoff reflect statistics that characterize real storms in real places.
