Multifractality of Cloud Base Height Profiles

نویسنده

  • K. Ivanova
چکیده

Cloud base height profiles measured with laser ceilometer are studied using multifractal approach. The irregular structure of the signals is a benchmark for nonlinear dynamical processes. A hierarchy of generalized dimensions determines the intermittency of the signal. The multi-affine properties are described by the h(γ) function.

NOTES AND CORRESPONDENCE An Automated Algorithm for Detection of Hydrometeor Returns in Micropulse Lidar Data

A cloud detection algorithm for a low power micropulse lidar is presented that attempts to identify all of the significant power returns from the vertical column above the lidar at all times. The main feature of the algorithm is construction of lidar power return profiles during periods of clear sky against which cloudy-sky power returns are compared. This algorithm supplements algorithms desig...

Improved algorithm for detecting cloud layers and amounts using retrievals from a surface-based multifrequency profiling radiometer

This paper will explore the possibility of using vertical profiles of temperature and relative humidity retrieved by a surface-based multifrequency profiling radiometer to determine the bases and tops of clouds as well as amounts (sky cover) of individual layers using a technique originally developed by Chernykh and Eskridge (CE) for radiosonde profiles. The CE method determines the presence of...

Multifractal behavior of the Korean stock-market index KOSPI

We investigate multifractality in the Korean stock-market index KOSPI. The generalized qth order height-height correlation function shows multiscaling properties. There are two scaling regimes with a crossover time around tc = 40 min. We consider the original data sets and the modified data sets obtained by removing the daily jumps, which occur due to the difference between the closing index an...

Cloud Base Height Estimation Using a Low-cost Digital Camera

 Cloud height, wind speed and direction at cloud height play an important role in air safety. This paper presents a low-cost system based on digital consumer cameras to estimate cloud base height. It is shown that both wind speed and direction at cloud level can also be obtained with this system. The method is based on triangulation and uses image registration to identify common cloud features...
