Nowcasting lightning occurrence from commonly available meteorological parameters using machine learning techniques

Electrical thunderstorm nowcasting using lightning data mining

This paper presents a study developed at SIMEPAR (Paraná state weather service) using lightning data for electrical thunderstorm nowcasting. Thunderstorm electrical data collected at SIMEPAR such as lightning location, time of occurrence, current intensity, polarity, etc, are stored in real-time in a relational database. As a first step of this study, Microsoft Business Intelligence bundled wit...

Global solar radiation estimation from commonly available meteorological data for Bangladesh

In this study, several regression models were employed to estimate global solar radiation from commonly available meteorological data such as sunshine duration, temperature, precipitation, and cloud cover for 34 meteorological stations of Bangladesh. The models studied were calibrated using five meteorological stations that are providing global solar radiation as well as other meteorological da...

Convolutional LSTM Network: A Machine Learning Approach for Precipitation Nowcasting

The goal of precipitation nowcasting is to predict the future rainfall intensity in a local region over a relatively short period of time. Very few previous studies have examined this crucial and challenging weather forecasting problem from the machine learning perspective. In this paper, we formulate precipitation nowcasting as a spatiotemporal sequence forecasting problem in which both the in...

Automatic particle selection from electron micrographs using machine learning techniques.

The 3D reconstruction of biological specimens using Electron Microscopy is currently capable of achieving subnanometer resolution. Unfortunately, this goal requires gathering tens of thousands of projection images that are frequently selected manually from micrographs. In this paper we introduce a new automatic particle selection that learns from the user which particles are of interest. The tr...
