The coldest cloud-top 10.3 \u00b5m infrared brightness temperature of the first (larger) pyroCb was around -56\u00baC (lighter shade of red), followed by a second (smaller) pyroCb exhibiting a minimum 10.3 \u00b5m brightness temperature around -47\u00baC (brighter shade of cyan). Surface analyses<\/strong><\/a> indicated that a large area of low pressure was expanding northward from northern Argentina to eastern Bolivia during the day — which likely brought an influx of warmer temperatures across eastern Bolivia (potentially creating a more favorable fire environment).<\/p>\n
