-resolution Doppler lidar able to map in three dimensions the coherent structures in the PBL. The target of the present paper is therefore to (i) investigate the multiscale nature of the turbulent eddies in the SL; (ii) to explain the existence of a −1 power law in the velocity fluctuation spectra already shown in Drobinski et al. (2004) ; and (iii) to investigate the different nature of turbulence in the two sublayers within the SL defined by Drobinski et al. (2004) , which are the eddy surface layer (ESL

APD analog signals weredigitized at 100 MHz, resulting in an inherent minimumrange resolution of 1.5 m. No attempt was made tostabilize the system for ship movement, making detailed observations problematic within the boundarylayer except in the calmest seas.3.

Over the Tibetan Plateau, however, vertically and temporally resolved measurements of cirrus cloud properties are still scarce, whereas the cloud-top and tropopause relationships by Cloud–Aerosol Lidar and Infrared Pathfinder Satellite Observations ( CALIPSO ; http://www-calipso.larc.nasa.gov/ ) ( Pan and Munchak 2011 ) and case study of cirrus cloud properties by balloon ( Tobo et al. 2007 ) has been reported recently

as the cloudiness (radar, lidar, and satellite remote sensing), and sample regimes of both deep and shallow convection. With the limited sample size in mind, we do not provide a quantitative relationship between the variation in cloudiness and the vertical velocity. Instead, we put forward the argument that to understand the variability in mesoscale cloudiness, the circulation at that scale is something that we cannot ignore. Observations from the Elucidating the Role of Cloud

different meteorological conditions, both at the surface and throughout the mixed layer (ML) and the EL. The observations should provide not only measurements of profiles and gradients of atmospheric variables but also their turbulent fluctuations. Reaching the CBL top is possible with aircraft in situ or remote sensing instrumentation as well as ground-based, vertically steering, or scanning lidar or clear-air radar systems. Unfortunately, dedicated observations for studying LES and TPs are relatively

, however, the values differ significantly, showing a much smaller intermittency and higher H and exponents in the observational data. Partly these differences can be explained by observational limitations and will be discussed in the following section. b. Sensitivity to observational limitations In this section, we use the numerical simulation as a surrogate data source to address the impact of three intrinsic limitations of lidar observations on the structure function analysis: the domain size

In addition to the observational datasets, 700-hPa analyses from the European Centre for Medium-Range Weather Forecasts (ECMWF) Integrated Forecast System (IFS) are used here to provide the context of the large-scale synoptic flow. 3.
