    Note:
    1. Categorization of temperature/rainfall is based on the normal distribution constructed from climatological data in the previous 30 years. The categories are defined in such a way that the highest 30% and the lowest 30% of the normal distribution are classified as "above-normal" and "below-normal" respectively, while the middle 40% represents the normal range.
