    A Knowledge-Based Strategy for Interpretation of SWIR Hyperspectral Images of Rocks by Frank J. A. van Ruitenbeek, Wim H. Bakker, Harald M. A. van der Werff, Christoph A. Hecker, Kim A. A. Hein, Wijnand van Eijndthoven

    Published 2025-07-01
    “…We developed an innovative, knowledge-based strategy to perform mineralogical analyses and create classifications that overcome this problem by using physics-based wavelength positions of absorption features that are invariant between scenes as the main sources of mineral information. The strategy to interpret short-wave infrared hyperspectral images of rocks is implemented using the open source Hyperspectral Python package (HypPy) and demonstrated on a series of hyperspectral images of hydrothermally altered rock samples. …”

    Comparison of the Structural Characteristics of the the Jiulong Vortex Continuing to Move Northeast and Stagnating in the Sichuan Basin by Chunhua ZHOU, Dixiang XIAO, Shuhua YU

    Published 2022-10-01
    “…With on-site observation data, NCEP reanalysed data and annual statistical results of the Southwest Low Vortex, we checked information of the Southwest Vortex activities in the past ten years, The moving of the Kowloon vortex from the vortex source area and moving to the northeast through Sichuan Basin is called the moving out type.The one with little stagnation in Sichuan basin after the Kowloon vortex moves out of the vortex source area is called stagnation type, classified the vortex sources and paths, and focused on comparative analysis of characteristics between moving-out type and stagnant type of Jiulong Vortex activities, such as circulation situation, heat change and power wave.The conclusion is as below, (1) at 200 hPa level, for moving-out type, main position of South Asian High Pressure is further south and the strength is weaker, the position of high altitude jet is further south and strength is stronger, mid-latitude area has low groove and low vortex is located in front of high altitude groove and on the right of high altitude jet entry point.While for the stagnant type, low vortex is located near the east side of the central South Asian High Pressure.(2)At 500 hPa level, both moving-out type and stagnant type is in the situation of two grooves and one ridge in mid and high altitude at the beginning, as low vortex develops, moving-out type deepens the grooves in Beihu and stagnant type is controlled by high ridge in Beihu.Low groove in low vortex of moving-out type is deeper, southwest airflow in front of the groove leads low vortex at lower level move northeast, while stagnant type stays in the situation of “high in the east low in the west”, thus low vortex sustains in Sichuan for a long time.(3)Regarding heat change and power wave characteristics, both types shares the principle “central warm structure” in all altitude at the beginning, at the peak period it changes at high verto “central cold structure” at low altitude while it maintains “central warm structure” at high altitude.The impact of non-adiabatic heating is very obvious at the beginning and peak period.The sensitive heating rate of moving-out type is much stronger than stagnant type, while latent heating rate of moving-out type is much weaker than stagnant type.Another difference is that there are fronts in low vortex for moving-out type and the atmosphere potential is unstable, while there is no fronts in low verex for stagnant type, the moist layer is much thicker.…”
