We show how a general formulation of the Fluctuation-Response Relation is able to describe in detail the connection between response properties to external perturbations and spontaneous fluctuations in systems with fast and slow variables. The method is tested by using the 360-variable Lorenz-96 model. where slow and fast variables are coupled to one another with reciprocal feedback. ... https://parisnaturalfoodes.shop/product-category/vitd3-400-iu-liquld/
