🇰🇬Kyrgyzstan

Kyrgyzstan spans 39°11′–43°16′N, a landlocked Central Asian country covering approximately 199,951 km² bordering Kazakhstan, China, Tajikistan, and Uzbekistan, dominated by the dramatic Tian Shan and Pamir-Alay mountain systems with about 94% of land above 1,000 m elevation.

The highest peak is Jengish Chokusu (Pik Pobedy) at 7,439 m on the Chinese border, the world's most northerly 7,000-plus-metre summit, with other key features including Khan Tengri at 7,010 m, the Issyk-Kul lake basin at 1,608 m elevation hosting the world's second-largest mountain lake that never freezes thanks to slight salinity, the Fergana Valley fringe in the southwest, and the Chuy Valley northern plain containing Bishkek.

The climate is dominated by altitude — humid continental (Dfa / Dfb) in the lower valleys, cold semi-arid (BSk) in rain-shadow basins including Issyk-Kul and Naryn, subarctic and alpine (Dfc / ET) at higher elevations, and ice cap (EF) on the highest peaks with extensive glaciation.

Bishkek averages −3°C in January and 25°C in July with 450 mm annual rainfall peaking in spring; Cholpon-Ata on the Issyk-Kul shore records −3°C and 17°C with 320 mm, moderated by the deep lake; Karakol at 1,770 m near the lake's eastern end −10°C and 17°C with 470 mm; Naryn at 2,041 m elevation −15°C and 17°C with 320 mm, making it Kyrgyzstan's coldest provincial capital; Osh in the Fergana Valley fringe −3°C and 27°C with 380 mm.

The Tian Shan summits average −20°C year-round with permanent ice, and Pik Pobedy reaches −30°C. Major events include the severe 1992 Sary-Tash earthquake-triggered landslides, recurrent severe Issyk-Kul rapid lake-level swings, intensifying summer Tian Shan glacier retreat with approximately 25% of Kyrgyz glacier area lost since the 1970s, growing glacial lake outburst flood hazard with the severe 1998 Issyk-Kul tributary events, Ala-Archa flash floods, and accelerating water stress in the Fergana margin as glacier-fed rivers including the Naryn and Kara Darya decline.

Our archive covers 3 Kyrgyz cities with daily ERA5 reanalysis data going back to 1940. The warmest July averages occur in Osh, around 31.8°C, while Osh records the coldest January nights near −6.5°C. Comparing the last decade against the 1940–1970 baseline, mean temperatures across these cities have risen by about 1.4°C.
