abstract = {Numerical weather prediction (NWP) models solve a system of
partial differential equations based on physical laws to
forecast the future state of the atmosphere. These models
are deployed operationally, but they are computationally
very expensive. Recently, the potential of deep neural
networks to generate bespoke weather forecasts has been
explored in a couple of scientific studies inspired by the
success of video frame prediction models in computer vision.
In this study, a simple recurrent neural network with
convolutional filters, called ConvLSTM, and an advanced
generative network, the Stochastic Adversarial Video
Prediction (SAVP) model, are applied to create hourly
forecasts of the 2 m temperature for the next 12 h over
Europe. We make use of 13 years of data from the ERA5
reanalysis, of which 11 years are utilized for training and
1 year each is used for validating and testing. We choose
the 2 m temperature, total cloud cover, and the 850 hPa
temperature as predictors and show that both models attain
predictive skill by outperforming persistence forecasts.
SAVP is superior to ConvLSTM in terms of several evaluation
metrics, confirming previous results from computer vision
that larger, more complex networks are better suited to
learn complex features and to generate better predictions.
The 12 h forecasts of SAVP attain a mean squared error
(MSE) of about 2.3 K2, an anomaly correlation coefficient
(ACC) larger than 0.85, a structural similarity index (SSIM)
of around 0.72, and a gradient ratio (rG) of about 0.82. The
ConvLSTM yields a higher MSE (3.6 K2), a smaller ACC
(0.80) and SSIM (0.65), and a slightly larger rG (0.84). The
superior performance of SAVP in terms of MSE, ACC, and SSIM
can be largely attributed to the generator. A sensitivity
study shows that a larger weight of the generative
adversarial network (GAN) component in the SAVP loss leads
to even better preservation of spatial variability at the
cost of a somewhat increased MSE (2.5 K2). Including the
850 hPa temperature as an additional predictor enhances
the forecast quality, and the model also benefits from a
larger spatial domain. By contrast, adding the total cloud
cover as predictor or reducing the amount of training data
to 8 years has only small effects. Although the temperature
forecasts obtained in this way are still less powerful than
contemporary NWP models, this study demonstrates that
sophisticated deep neural networks may achieve considerable
forecast quality beyond the nowcasting range in a purely
data-driven way.},
