The document discusses several studies on predicting rainfall through machine learning techniques.
It first summarizes four studies that proposed different methodologies for rainfall prediction, including using artificial neural networks, feedforward multilayer perceptron networks, and K-nearest neighbor and self-organizing map classifiers.
It then summarizes a study that used instrumented high-altitude balloons and machine learning to predict winds aloft and test the accuracy of wind projections, with the goal of wind forecasting.
