Based on the University of Utah Tropical Rainfall Measuring Mission (TRMM) precipitation feature (PF) database, tropical cyclone PFs (TCPFs) are identified for over 600 storms that reached tropical storm intensity level or above around the globe during eight TC seasons from the period of 1998–2006. Each TC season includes 6 months yr. Six basins are considered: Atlantic (ATL), east-central Paci...

Complex orography is still a big challenge for all numerical weather prediction (NWP) models. Orography an important factor that affects the NWP results. The in mainly main accuracy of results through two aspects: orographic representation models dynamics and orography-related parameterization schemes physical processes. To ensure results, it necessary to have comprehensive understanding applic...

The Northwest Pacific (NWP) anomalous anticyclone (AAC) intensifies and extends northward from El Niño decaying early to mid-summer, despite Niño-induced sea surface temperature (SST) anomalies in the North Indian Ocean, Atlantic subtropical NWP. present study suggests intra-seasonal variations of AAC are induced by local mean state changes investigates underlying mechanisms perspective energet...

A feed-forward, supervised, multi-layer perceptron Artificial Neural Network (ANN) was developed to test the following hypothesis: An ANN can be developed to successfully forecast thunderstorm activity up to 24 hours in advance, and with a spatial accuracy of 20-km, wherein ANN inputs include selected output from (1) deterministic mesoscale Numerical Weather Prediction (NWP) models, and from (2...

radioactive waste is currently the preferred means of disposal for many countries worldwide. The role of ESD's Nuclear Waste Program (NWP) is to assist the U.S. Department of Energy, the United States, and other countries in achieving the safe disposal of high-level radioactive waste—by means of high-quality scientific analyses that encompass modeling, laboratory and field experiments, and tech...

The steady path of doubling the global horizontal resolution approximately every 8 years in numerical weather prediction (NWP) at the European Centre for Medium Range Weather Forecasts may be substantially altered with emerging novel computing architectures. It coincides with the need to appropriately address and determine forecast uncertainty with increasing resolution, in particular, when con...

Accurate rainfall forecasts using numerical weather prediction (NWP) models can provide significant increases in forecast lead-time and thereby give greater opportunity for flood warning and protection measures. One goal of the FLOODRELIEF project is to quantify the uncertainty of forecast precipitation fields from two different NWP models (Eta and MM5) to investigate the impact of precipitatio...

Radio wave propagation on low-altitude paths over the ocean above 2GHz is significantly affected by negative refractivity gradients in the atmospheric surface layer, which form what is often referred to as an evaporation duct (ED). Refractivity from clutter (RFC) is an inversion approach for the estimation of the refractivity profile from radar clutter, and RFC-ED refers to its implementation f...

[1] This paper examines monthly variability of climatological mean sea surface temperature (SST) in the Black Sea. A total of eight products, including observationand model-based SST climatologies, are formed and compared with each other. Some of the observation-based SST data sets include only satellite measurements, while others combine in situ temperatures, such as those from moored and drif...
