Introduction to the Lecture:

Rising global temperatures, changes in the hydrological cycle and increased frequency of natural disasters threaten the Earth's ecosystems, economies, and infrastructure. Responding to these changes requires advanced and innovative telemetry and artificial intelligence technologies, which we apply to study hydrometeorological hazards and environmental and ecological issues such as droughts, typhoons, and floods, e.g. by the development of new empirical formulae (Liou-Liu formula) to explain the interactions between meteorological systems; and the development of new indices such as the Normalized Differential Latent Heat Index (NDLI) and the Temperature-Moisture-Drying of Soil (TMDI) indices to analyze surface water availability and thermal status, which have shown advantages in drought assessment. The above techniques have been applied to study the impact of climate change on typhoons in the Northwest Pacific Basin and to assess the impact of typhoons on countries and regions, such as typhoon landfall in Vietnam and vulnerability in Taiwan; and to study drought conditions, including Mongolia, Ethiopia, India and other regions. The results of the research have highlighted the importance of remote sensing and artificial intelligence technologies for sustainable development and global environmental protection, providing critical information and tools for building sustainable and resilient societies that contribute to the conservation and sustainable development of the Earth's ecosystems.
