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.

2. Rainfall prediction could be very vital in several elements of
our economic system and may assist us stopping serious
herbal disasters. Some regions in India are economically
depending on rainfall as agriculture is number one career
of many states. This enables to discover plants styles and
correct control of water assets for the plants. For this, linear
and non-linear fashions are usually used for seasonal
rainfall prediction
3. • To predict rainfall to prevent flooding that saves people's
lives and propert
• To predict the quantity of rain in a specific division in
advance by using various regression
• Reduce the time and effort involved in the process.

new modeling technique using artificial
neural networks. Artificial neural
networks are especially useful where
the dynamical processes and their
interrelations for a given phenomenon
are not known with sufficient accuracy
It is shown that the generalized

prediction of annual mean rainfall.
Immediate application and potential
of such a prediction system are
discussed.

The prediction of Indian summer

scales
the network designed for the present
study consists of 4 layers input(25
neurons which are previous five years
values from each time series of
monthlymeans ISMR values from of
June, july, August and september and
the seasonal mean), output(1 neuron,
the next year value from oany one the
time series under consideration) and
two hidden(2 and 4 neurons),
The present study has for the first
time, shown that monthly rainfall
during the monsoon season can be
predicted with sufficient Lead time
and good skill. This indicates that it
may be possible to develop a
suitably configured neural network
for predicting monsoon rainfall on
suitably defined regional scale.

anticipated trajectory with the sensed
winds, we can test the learnt
prediction model in the field.

winds deviates sharply from NOAA
projections.
2. Path Prediction: we were able to confirm
the accuracy of the projected winds.

C.I. Christodoulou Clouds that backscatter more
electromagnetic radiation
consist of larger droplets of rain and
therefore they produce more rain.
Using the radar data as input and the rain
gauge readings as output, the statistical KNN
classifier and the neural SOM classifier were
constructed for the classification job. With an
average inaccuracy rate of 23%, the radar
reflections were used to estimate the rate of
rainfall on the ground.
The findings of the current study
imply that it is feasible to estimate
the rate of rainfall using weather
radar recordings and a
methodology based on KNN and
SOM classifiers.

6. • Prediction accuracy is very less
• Finding the precipitation is particular to a geographic area.
• Works only for linear datasets and does not work for the
non linear datasets.
• Works well only on small scale of datasets through which it
was not able to predict the rainfall for larger datasets.
7. • High prediction accuracy.
• Hold perfectly good for large scale datasets with large number of
variables.
• Deals efficiently with data having missing values.
• Can be used for unsupervised learning and outlier detection.
