Evaluation and Improvement of a Stochastic Parametric Tropical Cyclone Rainfall Model - for Flood Impact Assessment

BaCla is a new stochastic parametric precipitation model to estimate rainfall associated with Tropical cyclones (TCs) in a computationally efficient way. It is validated for a number of calibration cases along with the current benchmark IPET deterministic method. The results of these models are compared with the observed StageIV-based rainfall....

Parametric Precipitation Model for Tropical Cyclone Radial Rainfall Profiles: Reducing the biases in the Bader model for the North Atlantic

Torrential rain from tropical cyclones can have a devastating impact, causing loss of life and billions in damages. To better understand the risk faced by coastal communities, it is important to estimate how often a tropical cyclone could occur and how much rainfall it will produce. One way to do this is by analyzing past storms and building...

Creation of new Extra-Tropical Cyclone fields in the North Atlantic with Generative Adversarial Networks: A deep learning framework to generate new synthetic atmospheric variables fields from the learned original sample data distribution

Extra-Tropical Cyclones (ETCs) are major storm system ruling and influencing the atmospheric structure at mid-latitudes. These events are usually characterized by strong winds and heavy precipitation and cause considerable storm surges with threatening wave systems for coastal regions. The possibility to simulate these storms or to increase the...

Storm Surge Modelling due to Tropical Cyclone Activity: Development of an artificial neural network capable of predicting maximum storm surge heights for Hong Kong and Macau

Over the recent years, flood risks and losses have been increasing for coastal cities due to climate change, subsidence, population and economic growth. Hong Kong and Macau are two cities located in the Pearl River Delta that experience a significant flood risk due to storm surges. The increased losses and risks has sparked interest around the...

Improving the sea defense of Central Termoeléctrica Antonio Guiteras

The central Thermo Electrico Antonio Guiteras (CTE Antonio Guiteras) is a thermoelectric power plant located in the bay of Matanzas. In 2017, hurricane Irma passed the north coast of Cuba and destroyed the primary sea defense in front of the CTE, causing major damage to the plant. The power plant is renovated, and a new and improved sea defense...

Including stochastic rainfall distributions in a probabilistic modelling approach for compound flooding due to tropical cyclones: A case study for Houston, Texas

Hurricanes impose great threats on coastal communities in terms of hazard and impact. Recent hurricanes like Harvey (Texas, 2017) and Idai (Mozambique, 2019) emphasize the global character of this threat. In the U.S., Hurricane Harvey tied with 2005's Hurricane Katrina as the costliest tropical cyclone on record, inflicting $125 billion in...

Flood Risk Assessment of the Clear Creek Watershed considering compound events

Tropical cyclones generate risk of compound flooding in coastal watersheds due to both precipitation and storm surge. For regions prone to this phenomenon, it is clear that in order to properly quantify flood hazard...

Computationally Efficient Modelling of Compound Flooding due to Tropical Cyclones with the Explicit Inclusion of Wave-Driven Processes: Research into the required processes and the implementation within the SFINCS model

Tropical cyclones (TCs) have tremendous impact on coastal communities in terms of damage due to flooding and high wind velocities, as shown by the recent hurricane season of 2017. Coastal flooding due to TCs can be contributed to different types of forcing (e.g. high offshore water levels, rainfall, etc.), or multiple at the same time (i.e....

A study on the environmental state of the Caribbean Sea in relation to the rapid intensification of tropical cyclone Matthew

Tropical cyclones have the ability to very quickly increase in strength. This process is called rapid intensification and as a result, tropical cyclones can transform into hurricanes. Rapid intensification is related to the availability of heat and the amount of negative feedback of the ocean on the tropical cyclone. Negative feedback results in...
