Monthly Diffusion v0.9: A Latent Diffusion Model for the First AI-MIP

Monthly Diffusion v0.9 (MD-1.5 version 0.9) is a climate emulator leveraging a spherical Fourier neural operator (SFNO)-inspired Conditional Variational Auto-Encoder (CVAE) architecture to model low-frequency internal atmospheric variability using latent diffusion. Designed for monthly mean timesteps in a data-sparse regime with modest computational requirements, MDv0.9 enables stable emulation of the atmosphere for several decades at relatively low GPU cost, although challenges remain in extrapolation beyond the training domain.

Executive Impact

MDv0.9 demonstrates significant performance and efficiency gains over traditional models, making long-term climate simulations more accessible and faster. Its design prioritizes low computational cost and stable decadal-scale rollouts.

372 Training Samples

Despite being trained on a highly restricted dataset of only 372 monthly samples, MDv0.9 successfully performs stable auto-regressive ensemble experiments for 46.25 years, showcasing remarkable data efficiency.

While MDv0.9 offers compelling advantages in computational efficiency, initial evaluations reveal areas for refinement, particularly in accurately reproducing specific atmospheric phenomena and teleconnection patterns compared to ERA5 reanalysis data.

Feature MDv0.9 Capabilities Areas for Improvement
Atmospheric Circulation
  • Reasonable climatological spatial distributions.
  • Robust NAO-like modes with good spatial patterns.
  • Overly strong meridional temperature gradient.
  • Enhanced midlatitude jets and polar vortex compared to ERA5.
  • Weaker stratospheric zonal wind.
Precipitation & Temperature
  • Reasonable climatological distributions.
  • Correct global-mean response to SST forcings.
  • Less precipitation in ITCZ, enhanced in specific regions (NW South America, SE Asia).
  • Spectral noise.
  • Struggles over mountainous regions.
  • Colder tropical stratosphere / warmer tropical/midlatitude troposphere.
ENSO Teleconnections
  • Displays reasonable patterns over global oceans.
  • Significantly reduced strength and teleconnections across continents compared to ERA5.
Computational Cost & Stability
  • Low GPU cost.
  • Fast auto-regressive ensemble rollouts (46.25 years in ~20 minutes).
  • Challenges remain in extrapolation beyond the training domain.
  • Requires sufficient 'spin-up' time (at least a decade).

MDv0.9 is positioned as a pivotal tool for advanced climate research, particularly within projects like the AI Model Intercomparison Project (AI-MIP). Its unique capabilities allow for rapid exploration of long-term climate scenarios and internal variability.

Accelerating AI-MIP with Efficient Climate Emulation

Challenge: Traditional global weather emulators and climate models operate at sub-daily timesteps, leading to high computational costs for long-duration, multi-ensemble climate simulations required by initiatives like AI-MIP. Assessing internal atmospheric variability and responses to various oceanic forcings over decades is prohibitive.

Solution: MDv0.9 provides a monthly-timestep, latent diffusion-based climate emulator that focuses on slow-evolving modes of internal atmospheric variability. Its low GPU cost and efficient auto-regressive rollout capabilities enable rapid generation of decadal-scale ensemble experiments.

Impact: MDv0.9 significantly lowers the computational barrier for long-timescale climate emulation, allowing researchers to quickly run 46.25-year, 20-member historical and SST-forced simulations. This accelerates the assessment of atmospheric responses to uniform global SST increases and internal variability patterns like the NAO, supporting comprehensive climate intercomparison projects.
