The document describes the Asian Australian Monsoon Time Scale, which is a chronological sequence of events arranged in a scale to study the past, present, and future movements of the Asian Australian monsoon and its relationship to weather patterns. It involves preparing a graphic scale from March 21st to March 20th of the following year, and noting major weather events each year to analyze monsoon trends and impacts over long periods of time. Studying the time scale can reveal patterns in monsoon rainfall, droughts, floods and other weather phenomena.
