Welcome to the
NatHaz On-line Wind Simulator (NOWS) website.
NatHaz On-line Wind Simulator (NOWS) provides user with on-line simulation of
stationary Gaussian multivariate wind fields on-the-fly.
With the help of rapid development of Internet/information technologies,
NOWS enables user to simulate stationary random wind fields at any time/space through network-enabled computer system and
general web browser. In addition, intuitive user-friendly interface and result interface makes user easy to input any terms and
to check simulation results such as display of simulated wind histories.
NOWS features supporting
both Metric (SI) and English units as input/output with on-line unit converter,
location inputs for
vertical,
horizontal or
arbitrary coordinates,
ASCE 7-based mean wind calculation considering terrain roughness to minimize user's input,
offering to download simulation results providing user with further off-line analysis
such as structural dynamic analysis under wind loads.
In particular, one unique feature of this on-line analysis module is the flexibility of selecting one of
four simulation schemes.
