V. Protasov, V. A. Ogorodnikov] Using variational information assimilation, we propose the method of dynamic probabilistic numerical investigation of the climatic sensitivity of atmospheric processes to their long-term perturbations in given regions. We use the known representation of the atmosphere climate as a statistical ensemble of possible realizations of space-time meteoelement fields. In essence, we propose an algorithm for the approximate numerical modelling of conditionally distributed realizations by variational information assimilation methods using a numerical model of atmosphere hydrothermodynamics.
