Title: "From Laboratory to Application: A Survey of Data-Driven Weather
Forecasting"
by
Mr. Hao CHEN
Abstract:
The explosive maturation of deep learning has catalyzed a profound paradigm
shift in Earth system science, fundamentally disrupting the numerical weather
prediction (NWP) frameworks that have dominated atmospheric modeling for over
half a century. This survey provides an exhaustive, end-to-end panoramic
analysis of the rapid evolution of data-driven weather forecasting. Tracing
the trajectory from early laboratory proof-of-concept explorations to critical
operational deployments in premier global meteorological centers, we establish
a rigorous, mutually exclusive four-stage classification system: early
data-driven exploration, reanalysis-based forecasting, real-data integration,
and operational commercial services. By systematically evaluating foundational
data infrastructures and standardized benchmarking ecosystems, we delineate
the data cornerstones driving algorithmic breakthroughs. Furthermore, we
meticulously dissect advanced artificial intelligence architectures across
diverse atmospheric applications, spanning from tropical cyclone tracking to
extreme precipitation nowcasting. Despite unprecedented computational
acceleration and deterministic accuracy, data-driven models continue to
grapple with severe structural vulnerabilities, notably the systematic
underestimation of extreme weather intensity, physical inconsistency, and
rapid error accumulation at subseasonal scales. To transcend these
limitations, this survey synthesizes cross-disciplinary insights to propose a
mathematically rigorous blueprint for future research. We advocate for
physics-guided continuous latent alignment, adaptive sparse-orthogonal
processing for ultra-high-resolution grids, and memory-anchored continuous
state-space forecasters to conquer the 'predictability desert'. Ultimately,
this document serves as a foundational roadmap guiding the development of the
next generation of highly reliable, physically consistent, and operationally
autonomous AI weather prediction systems.
