Outline

This paper presents a novel algorithm and dataset to solve the difficulties of weather heat map interpretation. Existing Vision-Language Models (VLMs) have difficulty in accurately interpreting weather heat maps with irregular outlines and complex color variations. In response, we propose a new algorithm, Sparse Position and Outline Tracking (SPOT), to handle irregularly shaped color regions. SPOT extracts spatial coordinates to represent irregular shapes in a structured manner. Based on SPOT, we construct a new weather visual question-answering (VQA) dataset, ClimateIQA, which consists of 26,280 high-resolution heat maps and 762,120 question-answer samples for analyzing wind speed, precipitation, perceived temperature, and discomfort index. ClimateIQA improves the accuracy of weather heat map interpretation by integrating spatial information, geographical metadata, and reanalysis data. Finally, we develop Climate-Zoo, a collection of fine-tuned VLMs utilizing SPOT and ClimateIQA, which achieves better performance than existing models.

Takeaways, Limitations

Takeaways:
Presentation of SPOT algorithm for effectively handling irregularly shaped color areas
Building a large-scale VQA dataset, ClimateIQA, specialized for weather heat map analysis
Development of Climate-Zoo with improved performance over existing VLM
Contribute to the development of weather phenomenon analysis and prediction technology
Limitations:
Potential regional bias in the ClimateIQA dataset (lack of information about the regional distribution of the dataset)
Need to verify the generalization performance of SPOT algorithm to other types of weather data or images
Lack of application and performance evaluation of Climate-Zoo's real-world weather forecasting system
Limited to analysis of specific indicators (wind speed, precipitation, perceived temperature, discomfort index) rather than a comprehensive analysis of various weather phenomena.
