-latitude intervals over three continental land masses.Similarly, Garratt (1977) determined S0 over Australiafor 2.5- squares based on 30 vegetation classes. Their results may be used to determine the overallmean S0 (according to the technique just described)for all land surfaces, S0 being a parameter commonlyused in numerical models of the atmosphere, where the924 MONTHLY WEATHER REVIEW VoLu

highlights the strength of an idealized testing framework to shed light on the physics–dynamics interactions. This approach can also be used to analyze the effects of different physics–dynamics coupling schemes. 5. Intramodel coupling In this section, the focus is on intramodel coupling problems within the modeling system, where the coupling occurs via an exchange of boundary conditions that transmit fluxes through a physical interface (e.g., the ocean–atmosphere, land–atmosphere, ice–atmosphere, or

they can transition into a completely different cloud type. These modes may also occur in concert (e.g., stratocumulus-to-cumulus transition). 1) Dissipation by cloud thinning The primary factors that reduce the thickness of the saturated layer in which stratocumuli reside include the following: strong subsidence that can lower the inversion ( Randall and Suarez 1984 ), especially in coastal regions affected by land–sea interactions ( Sundararajan and Tjernstrom 2000 ); an increase in the

interactions Although theory provides some guidance, the question remains what makes a jet a good waveguide in the real atmosphere. The issue can be addressed by experimentation with numerical models. It turns out that the ducting property of a jet waveguide in a climate model depends on the strength of the jet stream ( Branstator 2002 ). This result was later corroborated by idealized simulations with a barotropic model, indicating that a jet must be strong and, in particular, narrow in order to make it a

( Blake et al. 2013 ). Contributions from both tropical and baroclinic energy sources caused Sandy to reintensify as it approached the coastline ( Galarneau et al. 2013 ; Shin and Zhang 2017 ). The TC followed an atypical track northwestward toward the Northeast United States, rather than out to sea, fostered by interaction with an upstream trough ( Barnes et al. 2013 ; Qian et al. 2016 ) of the type identified by Fujiwhara (1931) , the practical predictability of which depended on the modeling

injury, national media attention has been less than for their tropical cousins. Only a handful has been described in the literature ( Lynott and Cramer 1966 ; Reed 1980 ; Reed and Albright 1986 ; Kuo and Reed 1988 ; Steenburgh and Mass 1996 ), and questions remain regarding their mesoscale and dynamic evolutions, including interactions with terrain.

there(u and v out of phase) during northern winter.10. Oceans Along with the surface Wind stress, variations overthe Arabian Sea (Wylie and Hinton 1982) and the Pacific Ocean (Madden 1988), we should expect the effects of the oscillation to be manifest in the underlyingseas. Lau and Chan (1985, 1986b) proposed an atmosphere-ocean interaction as a possible link between theoscillation and the onset of the E1 Nifio. Krishnamurtiet al.
