Published 27.10.2020 The Yavlenka weather station in the North Kazakhstan region was opened in 1902. Until 1933, the weather station was called "Petropavlovsk agricultural College", and since 1933 it has been called"Yavlenka".
Phenological observations at the station began in 1937, and in 1938 instrumental measurements of soil moisture began. In the same year, on September 18, the station was moved to the South-East by 500m. The height of the weather station has not changed due to the transfer.
In the vicinity of the weather station there are protective forest strips and pegs, the main species of which were birch, aspen,elm. The weather site was located on the second terrace of the Ishim river on a flat place. To the Southeast, at a distance of 50 meters, there was a salt lake with an area of 2 km2 and a depth of up to 5 meters. Among other things, 140 meters to the West of the weather site was a garden, the main species of which were birch, pine, lilac, etc. Gradually, the garden grew, the surrounding area was built up, and due to the risk of data distortion, on October 12, 1999, the weather station was moved to another, more representative site, characteristic of the surrounding area.
Today, the weather site is located on the South-Western edge of the village. The station's weather site is located on a site with a natural vegetation cover for this area (mixed grasses), which is not disturbed when the weather site is set up.
