5 (3) Preliminary results Urban turbulence: Averaged HOST relations between wind speed V and friction velocity u * (each dot represents a 30-min averaged value) (a) at 47 m for three surface roughness ranges, where rough, medium, and smooth refer to wind direction ranges of , , and o, respectively; and (b) at 47 m and 140 m on nights following sunny days, with CASES- 99 HOST over grass and neutral MOST prediction slopes. Effects of urban canopy on turbulent mixing: similar to plant canopies, but more complicated. HOST (HOckey Stick Transition) hypothesis can be used to explain the observed turbulent momentum and heat transfers in urban areas Two unique features: -Direction-dependent z 0 - Fog/haze effects turbulence

6 Estimate of PBL depth using Doppler LiDAR data Fractional Methodology for SURF NBL-depths (+ s) Definitions: Near-surface max Assumed constants at PBL top Background f = 0.1 = 0.01 m 2 s -2 is min possible value in model s scheme Here, is averaged nighttime value above 1 km Results: NBL depths now look reasonable (details follow) Lidar measures u/v/w σ 2 is the variance of w indicating the turbulence strength

7 Improvement of urban model with SURF data Cooling Tower (CT) scheme was incorporated to BEP+BEM to improve the modeling of LE. (with J. E. Gonzalez s CCNY Team) AMS-2017: Improving the Representation of Latent Heat Fluxes on Operational Forecast Models for Beijing, China, M. Yu 7

8 Urban impacts on rainfall: Climatic analysis Weak-UHI cases: two western-max ( > 15%), Old Town-min ( < - 15 %) and urban rain-shadow (<-35%) are intensified Strong-UHI cases: UHI-induced two urban-max (75% & 60 %) over urban centers. Weak-UHI cases(< 1.5 C) Strong-UHI cases(> 1.5 C) Summer total rainfall anormaly

9 The distribution of aerosol number concentration based on 53 flights observation The concentration in PBL during both winter and summer show consistent number loadings at #/cc and effective diameter ~0.4um, suggesting generally consistent emission and uniform mixing of pollutants. The strong subsidence inversion on top of PBL in winter sometimes lead to substantially increased concentration ( um) >6000#/cc. After being removed by dynamic air conditions, the background aerosol number concentrations ( um) are consistent in summer and winter at #/cc.

10 Haze impacts on albedo: Observed (a) PM2.5 mass concentration at HAI, and albedo from 325 m tower at the height of (b) 47 m, (c) 140 m, and (d) 280m on 1 Dec and 4 Dec The albedo on haze day is largely greater than that on clear day The albedo increases with height no matter on clear or haze day. The difference of albedo between clear and haze day also increases with height. Haze could affect the radiation process and then stabilize the stratification.

12 (4) Future Plan 1. SURF data: QC and sharing 2. New equipment and new data The new network of ceilometers Soil moisture network Urban and weather satellite remote sensing In-situ thermal remote sensing 3. New sciences Interaction between urban and heat/cold wave Interaction between fog/haze and weather Interaction between urban and terrain (Phase II) 4. R2O: Research to Operation 5. Outreach, and Education 6. Phase II: SURF-MT( Mountain Terrain)

13 Phase II: SURF-MT (preliminary discussion) In order to answer the following questions: How can we combine radar, lidar, wind profilers, and other sensors to fill the gap between the city and the mountains? How does precipitation evolve once it is initiated in elevated terrains and moves to the city? What is the interaction between urban and terrain? Science Objectives Promote cooperative international-research to improve understanding of 4-D boundary-layer structure in mountain terrain via workshops & field studies Evaluate & improve high-resolution (~ m grids) numerical models Enhance forecast-utility for urban and mountain terrain, and for Winter Olympics applications
