  Tracks of typhoons are predicted using a generative adversarial network (GAN)
with observational data in form of satellite images and meteorological data
from a reanalysis database. Time series of images of typhoons which occurred in
the Korean Peninsula in the past are used to train the neural network. The
trained GAN is employed to produce a 6-hour-advance track of a typhoon for
which the GAN was not trained. The predicted image favorably identifies the
future location of the typhoon center as well as the deformed cloud structures.
The errors between predicted and real typhoon centers are measured
quantitatively in kilometers. 65.5 % of all typhoon center predictions have an
error of less than 80 km, 31.5 % lie within a range of 80 - 120 km and the
remaining 3.0 % are above 120 km. The overall error is 67.2 km, compared to
95.6 km when only observational data are used as input. The cloud structure
prediction is evaluated qualitatively. It is shown that the GAN is able to
predict trends in cloud motion. It is found that adding physically meaningful
meteorological data to satellite images improves the sharpness of predicted
images.
