Key Findings

01A family approach allows for modular development and targeted bias correction.
02Incorporating an Earth-System component requires addressing underlying climate biases.
03Stratospheric resolution can be varied within a model family.

Application

Design takeaway

How to apply

When designing a software suite, create a core engine and then develop specialized modules for different user needs or advanced features, allowing for independent updates and bug fixes.

Project actions

01When designing a product, think about its core function and then consider how different modules or features could be added or modified.
02If you encounter a problem with one part of your design, consider if it can be addressed by modifying a specific module rather than redesigning the entire system.

Method & Evidence

AimHow can a structured family of climate model configurations be developed to systematically address known biases and integrate advanced Earth-system components?

MethodModel development and evaluation

ProcedureThe HadGEM2 family of climate configurations was developed by creating a common physical framework with varying levels of complexity. This included atmosphere and ocean components, with and without stratospheric extension, and an Earth-System component. Specific improvements were made to address known biases from previous configurations, and performance was evaluated using metrics comparing simulations of present-day climate.

ContextClimate science and atmospheric modelling

Variables

IVModel configuration complexity (e.g., inclusion of stratosphere, Earth-system components)

DVModel performance metrics (e.g., Northern Hemisphere temperature bias, tropical sea surface temperature bias, variability)

CVCommon physical framework of the Met Office Unified Model

Strengths & Limitations

Strengths

+Comprehensive description of a complex modelling system.
+Clear methodology for evaluating model performance.

Limitations

The complexity of climate models means that the 'family' approach is highly specialized. Applying this directly to simpler design projects might be overkill.

Reliability & validity

The reliability of the findings is supported by the use of standardized model metrics for comparison. Validity is enhanced by the detailed description of the model configurations and the evaluation against observed climate data.

Think critically

What are the trade-offs between developing a single, highly integrated system versus a 'family' of interconnected but distinct systems?

Design Principles

"Modular development and iterative refinement of complex systems allow for targeted improvements and the integration of advanced functionalities."

This approach enables researchers and designers to iteratively refine models by isolating and correcting biases in specific areas, such as temperature or sea surface temperature, without compromising the integrity of the entire system. It facilitates the integration of advanced components like dynamic vegetation and atmospheric chemistry, crucial for understanding complex climate feedbacks.

What This Means for Your Design

Imagine building a video game. Instead of making one giant game, you make a core game engine and then create different versions or add-ons for specific features (like better graphics or new levels). This makes it easier to fix problems in one area without breaking the whole game.
