How it spread, pass by pass, and what the wind was doing
Each dot is a hotspot the satellite detected as it flew over. The hourly wind flows underneath.
Radiated energy (FRP) of each pass · gusts as the linelocal time · Asia/Yangon
Upper-level wind (850 and 700 hPa) is only available for fires from the last two weeks: the ERA5 archive we use has no pressure levels.

How it is calculated (for anyone who wants to check)
Pass: the hotspots from one satellite with less than 20 minutes between them. Spread: the distance from each new hotspot to the nearest earlier hotspot; we take the 90th percentile so a single stray hotspot cannot inflate the figure, and we only count the pass if at least 5 hotspots fall more than 750 m from what had already been seen (those more than 15 km away are another fire and do not count). Speed: the spread divided by the hours since the previous pass, only if 6 hours or more have gone by; it is a minimum, because the front may have moved faster and then stopped. Wind: the vector mean of the hours between the two passes, interpolated between the model grid points around the hotspots that moved. “With the wind” if the heading of the spread and the direction the wind blows towards differ by less than 60°, “crosswind” up to 120° and “against” beyond that.
