abstract = "The ADIFOR automatic differentiation tool is applied to a 3-D storm-scale
meteorological model to generate a sensitivity-enhanced code capable of providing derivatives of all
model output variables and related diagnostic (derived) parameters as a function of specified
control parameters. The tangent linear approximation, applied to a deep convective storm by the
first of its kind using a full-physics compressible model, is valid up to 50 min for a 1 \%
water vapor perturbation. The result is very encouraging considering the highly nonlinear and
discontinuous properties of solutions. The ADIFOR-generated code has provided valuable sensitivity
information on storm dynamics. Especially, it is very efficient and useful for investigating how a
perturbation inserted at earlier time propagates through the model variables at later times.
However, it is computationally very expensive to apply to the variational data assimilation,
especially for 3-D meteorological models, which potentially have a large number of input
variables.",
