Numerical Weather Models
Unisys 10-day model display for east Asia Includes whole eclipse track at half-day intervals. Click on individual time tab to see higher-resolution display. "Relative humidity" display shows integrated moisture through low and mid levels of atmosphere. High RH values (>70%) are correlated with a higher probability of cloud
Air Resources Laboratory meteograms Display of meteorological variables in chart form for user-specified locations (ICAO code for site or latitude-longitude) from US GFS model, out to 16 days. One available parameter is total cloud cover. Insert following ICAO codes to get station-specific forecasts: Shanghai (Pudong airport) - ZSPD; Shanghai (Hongqiao airport) -ZSSS; Wuhan - ZHHH; Chongqing - ZUCK; Hangzhou - ZHSC; Yakushima - RJFC; Amami - RJKA; Kwajalein - PKWA. Other locations will require latitude-longitude entry. Follow instructions carefully to get results.
Weatherzone Global numerical forecasts from Weatherzone in Australia, based on the GFS model. Select “International Charts” under “computer models” and then “Asia” on the tab above the map. Most relevant charts will be 850 mb (low level) and 700 mb (mid level) relative humidity. Forecasts extend to 180 hours (7.5 days). Charts are low-resolution but include both India and China.
Fleet Numerical Meteorology & Oceanography Center (FNMOC) U.S. Navy site with numerous global model displays. NGP and GFS models are available, but only NGP has display of relative humidity. Charts are detailed and difficult to decipher
Meteoblue site-specific model forecasts Meteograms of temperature, precipitation, wind, and cloud cover for 7 selected sites along the eclipse track. Includes a map of nearby areas that identifies the best (predicted) weather spot around the site.
7timer Forecasts for the globe based on a high-resolution Chinese model. Display is similar to the Clear Sky Clock; a special forecast is promised for the days leading to the eclipse. Site can be slow.
Hong Kong Observatory Numerical Forecasts High-resolution numerical forecast for eastern China and nearby waters, covering the eclipse track from Chongqing onward. Charts are available at 12-hour intervals out to 3 days. Surface "Weather" charts show cloud and precipitation. 700-mb charts show relative humidity at altitude.
