Verification of Satellite Derived Precipitation Estimates Over Complex Terrain: A Ground Truth Analysis for Nepal
Precipitation estimates from the satellite-based Tropical Rainfall Measuring Mission (TRMM) instrumentation play a key role in flood analysis and water resource management across many regions of the world where rain gauge data are sparsely available. Previous studies have produced conflicting …

Regional Differences in the Spatial Patterns of Precipitation Bands in Hurricanes Through Landfall along the Gulf of Mexico and Atlantic Coasts of the United States
… periods of precipitation distribution in tropical cyclones (TCs) are sometimes misrepresented in numerical weather prediction models due to the rapid nature of TC structure changes that accompany intensity change. To better understand quantitative changes in TC rainband structure around …

Numerical modelling of Tropical Cyclone Dineo and its rainfall impacts over north-eastern South Africa
… February 2017. The flooding was associated with Tropical Cyclone Dineo that was generated in the Mozambique Channel on 12 February 2017 and made landfall over the south-central coast of Mozambique on 15 February. This study investigates the atmospheric circulation and potential mechanisms …

Lightning/percipitation relationships on a global basis
Rainfall and lightning are measured and compared on a global basis using data gathered from the Tropical Rainfall Measuring Mission (TRMM) satellite, launched in November 1997. The satellite provides simultaneous lightning-precipitation measurements that allow for comprehensive relationships to be …

On the role of warm rain clouds in the tropics
… has been developed for warm rain clouds using Tropical Rainfall Measuring Mission (TRMM) satellite measurements. The algorithm uses TRMM Microwave Imager (TMI) brightness temperatures that have been deconvolved to the 19-GHz field-of-view (FOV) to retrieve cloud liquid water path (LWP), total …

Landslide susceptibility mapping through enhanced dynamic slope stability analysis using earth observing satellite measurements
… volcanoes, floods, and heavy continuous rainfall in mountainous regions. For most types of slope failure, soil moisture plays a critical role because increased pore water pressure reduces the soil strength and increases stress. The combined effect of soil moisture in unsaturated soil …

Tropical orographic rainfall regimes according to the tropical rainfall measuring mission
Observing precipitation in tropical regions of complex terrain is a challenging problem. While ground-based instrumentation including rain gauge networks and radar data offer some insights, the lack of spatially complete gauge networks and radar artifacts such as severe beam blockage lead to large …

Spatial and Temporal Distribution of Groundwater Recharge in the West Bank Using Remote Sensing and GIS Techniques
… models that are based on the long-term annual rainfall data. These models have been shown to be inadequate and changes over shorter periods, e.g. monthly estimates, must be known in order to study the temporal distribution of recharge. The approach used in this research integrates data derived …

Seasonal precipitation, river discharge, and sediment flux in the western Himalaya
Rainfall, snow-, and glacial melt throughout the Himalaya control river discharge, which is vital for maintaining agriculture, drinking water and hydropower generation. However, the spatiotemporal contribution of these discharge components to Himalayan rivers is not well understood, mainly because …

Investigation of the positive interaction between the primary and secondary circulation and the roles of different types of precipitation in tropical cyclone formation
Our understanding of tropical cyclogenesis, one of the greatest mysteries in tropical meteorology, has advanced significantly in the past few decades, partly owing to the availability of satellite data and high-resolution numerical model simulations. This research investigates the coupling among …
