Traders' near-unanimous consensus on a 20°C high temperature in Chongqing on March 21 stems from official observations from the China Meteorological Administration (CMA), which recorded a peak of exactly 20°C at key stations like Shapingba, aligning with ensemble model forecasts from ECMWF and GFS that projected mild conditions under partly cloudy skies and light winds. March climatology supports this, with historical highs averaging 17-19°C amid early spring warming, bolstered by recent satellite data showing stable atmospheric stability. A challenge would require a late-reported outlier from a peripheral station exceeding 21°C or a data revision, though CMA verification protocols make this improbable given the 0.1% market-implied odds.
