The possible impact mechanism is that the land cover changes could affect the surface energy partitioning, leading to a variation in the temperature distribution (i.e., the horizontal potential temperature gradient and boundary layer stability), in turn affecting the structure and evolution characteristics of the mountain circulation.Ĭonvection initiation (CI) has remained a major challenge in weather forecasting worldwide. GRASS shows the slightest change from the CNTL. DESERT shows the weakest valley breeze circulation with the longest duration. In the vertical direction, FOREST shows the strongest valley breeze circulation, with the largest horizontal and vertical extents of circulation, as well as the highest vertical extent of the updraft. The results show that the near-surface wind speed increases with decreasing surface roughness, and DESERT shows the most obvious change as compared with the CNTL. One control experiment (CNTL) and three sensitivity experiments, in which the current land cover is taken as areas of uniform evergreen broadleaf forest (FOREST), grassland (GRASS), and bare soil (DESERT) coverage, are conducted. Vertical cross-sections of turbulent heat, moisture and momentum fluxes show that turbulent transport plays an important role in the development and elimination of mountain-plain breeze circulation.įocusing on the complex underlying surface area in central–southern Hainan Island, this study uses the Advanced Research Weather Research and Forecasting Model (Version 4.0) to simulate a typical mountain circulation case without obvious weather system forcing, and tries to reveal the impacts of land cover changes on the mountain circulation. Stronger turbulences are formed over the mountain area compared to the plain area. Owing to this unique terrain feature, the north portion of the mountain demonstrates more evident mountain and plain breezes compared to the south and middle portions. The plain and mountain breezes can be predicted explicitly by the model, and the consequent circulations are coupled with other factors such as turbulent movement and vertically propagating mountain waves. Simulation results show that the 2 m temperature distribution of the plain and mountain areas is peculiar due to the occurrence of the temperature inversion. Turbulence characteristics are also examined to better understand the local circulation of the area. “Music is a good place to put your feelings.The spatiotemporal structure and evolution of the thermally-induced mountain-plain breeze circulation in the Longquan Mountain, eastern Chengdu, are studied by the WRF-ARW model based on a two-day case. “It’s an avenue of expression that’s the best part of music,” he said. Patrick Baron, a RHD-RI direct support professional and the band leader, explained why band members have so much fun together, whether playing for themselves or an audience. The band is composed of two staff members and several clients of Resources for Human Development Rhode Island (RHD-RI), a nonprofit, arts-based studio program serving adults with a range of disabilities. Unlike other bands, however, the Kings and Queens of Rock and Roll perform for free and remain hyper-local. The Valley Breeze has the scoop on this group from RHD-Rhode Island, a creative, fun, intellectually stimulating, art-based day program for people with developmental disabilities in a story titled “Kings and Queens of Rock and Roll release first album” The Kings and Queens of Rock and Roll, made up of clients at RHD Rhode Island and supported by staff, is dropping their first album.
