determinant of its optical properties ( Stephens 1978a ), it is a critical link between the cloud dynamics and radiative effects [Eq. (1) and discussion in section 4a below]. Liquid water mixing ratios q l typically increase with height in stratocumulus layers at a rate that is frequently quasi-linear and can approach that consistent with well-mixed conserved variables ( Fig. 10 ). The well-mixed rate is often referred to as the adiabatic liquid water profile. The adiabatic rate of increase of q

0 or 1; Murphy 1993 ). Thus, although authors seldom provide specific reasons for maximum values of q , this undesirable NEP property may have confined NEP applications to events that commonly occur within model climatologies. The next subsection describes methods that may be more appropriate for rarer events. b. A neighborhood approach to derive non-grid-scale probabilities 1) Methodology Whereas the neighborhood approach described in section 2a defines grid-scale events and yields grid

dynamics of the eyewall cloud. An expression for m ( r , p ) is substituted into (2) to determine the geometry of the streamlines. With the help of the basic equations of a symmetric vortex, one can obtain the magnitudes of the wind components, and the thermodynamic properties of the circulation of an idealized tropical cyclone vortex containing the eyewall cloud. The solution is based on the observation that the tropical cyclone circulation in the eyewall region tends to be conditionally

integrand. Furthermore, we just saw that the standard deviation of the estimate decreases as 1/ N . In contrast, gridpoint-based integration has the property that the rate of convergence decreases as the dimension of the integrand increases. c. …and perhaps why not? Obviously, for a million-dimensional system, the number of particles should also be large. How large is not exactly clear. A rule of thumb is that this number should be equal to the degrees of freedom of the system. However, in these large
