    AbstractIn (Chen, L., 2005. Vector time-varying autoregressive (TVAR) models and their application to downburst wind speeds. A PhD Dissertation, Texas Tech University, Lubbock, Texas.), a nonparametric deterministic–stochastic hybrid (NDESH) model was proposed for characterizing and simulating nonstationary thunderstorm downburst wind fields, and two sets of full-scale downburst wind speed records were fitted in this model. This paper aims to build an empirical numerical model for downburst wind fields according to the NDESH model and based on the results in (Chen, L., 2005; Chen, L., Letchford, C.W., 2005. Proper orthogonal decomposition of two vertical profiles of full-scale nonstationary downburst wind speeds. Journal of Wind Engineering and Industrial Aerodynamics 93(3), 187–216; Chen, L., Letchford, C.W., 2006. Multi-scale correlation analyses of two lateral profiles of full-scale downburst wind speeds, Journal of Wind Engineering and Industrial Aerodynamics 94(9), 675–696.), so that correlated downburst wind speeds can be synthesized from this empirical model.
