Special Issue Information

Dear Colleagues,

You know this perfectly well that turbulence as a phenomenon still remains an unsolved scientific problem, both from the point of view of mathematics and from the point of view of physics. At the turn of the millennium, among the ten unsolved problems of the 20th century, the problem of describing the motion of fluid and gas was named. From the standpoint of our journal, we single out the problem of turbulence precisely as the natural state of the atmosphere. For the atmosphere of the Earth, turbulence, as a phenomenon affecting the transfer of heat and angular momentum, remains constant in the list of the most important problems. Many instruments and tools installed in different parts of the world are constantly monitored, collecting data and, thus, providing material for building models and theories. These tools require constant development, their mutual coordination and calibration. Astronomers, geophysicists, acoustics,experts in weather forecasting, they are all constantly associated with the manifestations of this phenomenon, or more correctly, the state of our atmosphere as a gaseous medium, which is in a turbulent state.

In recognition of this milestone, the open-access journal Atmosphere is hosting a Special Issue to showcase current atmospheric turbulence models, measurement capabilities, and results.

Original results, review papers, new measurement equipments, data and turbulence model related to the simulation of turbulent dynamics and interaction, both inside and outside atmosphere, are all welcome contributions.

The main goals are for this Special Issue to be a useful starting point for students, a valuable snapshot of the overarching field for practitioners, and a means of stimulating model interoperability, multidisciplinary collaborations, and new functionality, across the entire hierarchy, from idealized process modeling, to regional, global, fluid-interior, and whole-atmosphere simulations, to planetary operational forecasting.

Sincerely,

Dr. Vladimir Lukin

In atmospheric turbulence, relative humidity has been almost a negligible variable due to its limited effect, compared with temperature and air velocity, among others. For studying the horizontal path, a laser beam was propagated in a laboratory room, and an Optical Turbulence Generator (OTG) was built and placed along the optical axis. Additionally, there was controlled humidity inside the room and measuring of some physical variables inside the OTG device for determining its effects on the laser beam. The experimental results show the measurements of turbulence parameters C n 2 , l o , and σ I 2 from beam centroids fluctuations, where increases in humidity generated stronger turbulence.

The paper focuses on the development of the method to estimate the mean characteristics of the atmospheric turbulence. Using an approach based on the shape of the energy spectrum of atmospheric turbulence over a wide range of spatial and temporal scales, the vertical profiles of optical turbulence are calculated. The temporal variability of the vertical profiles of turbulence under different low-frequency atmospheric disturbances is considered. Full article

In ultrasonic equipment (anemometers and thermometers), for the measurement of parameters of atmospheric turbulence, a standard algorithm that calculates parameters from temporary structural functions constructed on the registered data is usually used. The algorithm is based on the Kolmogorov–Obukhov law. The experience of using ultrasonic meters shows that such an approach can lead to significant errors. Therefore, an improved algorithm for calculating the parameters is developed, which allows more accurate estimation of the structural characteristics of turbulent fluctuations, with an error that is not more than 10%. The algorithm was used in the development of a new ultrasonic hardware-software complex, autonomous meteorological complex AMK-03-4, which differs from similar measuring instruments of turbulent atmosphere parameters by the presence of four identical ultrasonic anemometers. The design of the complex allows not only registration of the characteristics of turbulence, but also measurement of the statistical characteristics of the spatial derivatives of turbulent temperature fluctuations and orthogonal components of wind speed along each of the axes of the Cartesian coordinate system. This makes it possible to investigate the space–time structure of turbulent meteorological fields of the surface layer of the atmosphere for subsequent applications in the Monin–Obukhov similarity theory and to study turbulent coherent structures. The new measurement data of the spatial derivatives of temperature at stable stratification (at positive Monin–Obukhov parameters) were obtained, at which the behavior of the derivatives was been investigated earlier. In the most part of the interval of positive Monin–Obukhov parameters, the vertical derivative of the temperature is close to a constant value. This fact can be considered as a new significant result in similarity theory. Full article
