Study on Mesoscopic Damage Evolution Characteristics of Single Joint Sandstone Based on Micro-CT Image and Fractal Theory

Shock and Vibration, 2021
The different directions of joints in rock will lead to great differences in damage evolution characteristics. This study utilizes DIP (digital image processing) technology for characterizing the mesostructure of sandstone and combines DIP technology ...

Occurrence and characteristics of mesoscale eddies in the tropical northeastern Atlantic Ocean [PDF]

Ocean Science, 2015
Abstract. Coherent mesoscale features (referred to here as eddies) in the tropical northeastern Atlantic Ocean (between 12–22° N and 15–26° W) are examined and characterized. The eddies' surface signatures are investigated using 19 years of satellite-derived sea level anomaly (SLA) data.

The Precipitation Characteristics of Mesoscale Convective Systems Over Europe [PDF]

Journal of Geophysical Research: Atmospheres, 2023
AbstractMesoscale convective systems (MCSs) are common over Europe and can produce severe weather, including extreme precipitation that leads to flash floods. The few studies analyzing the climatological characteristics of MCSs over Europe are either focusing on only few years of data or on limited subareas.

Studying the influence of cold-core mesoscale ocean eddies on sound propagation based on the parabolic equation method

AIP Advances, 2023
Mesoscale vorticity is an important factor that affects the non-uniform horizontal and vertical distribution of hydrologic elements in the ocean. In this paper, temperature and salinity data from measured mesoscale cold-core eddies during a voyage within
