Kazakhstan has started updating its wind load map. The map will be fully renewed within 2-3 years, Tengrinews.kz reports citing KazHydroMet (national weather service).
According to the experts, the storm could have caused less damage, if the map was considered during construction of buildings in Zhambyl oblast. “Any construction process has to comply with the GOSTs (state standards) that considers the wind load among other things. The last update was made in 1985. This year we started updating the map. It will specify wind speeds area by area for the next 20 years. These parameters will have to be considered when buildings are designed and erected. Unfortunately, the climatic loads are rarely considered in private construction,” Paiyzkhan Kozhakhmetov, Director of Climate and Water Issues Research Department of KazHydroMet said.
According to first deputy Director General of KazHydroMet Tursynbek Kudekov, the works to update the map are planned to be completed within 2-3 years.
The experts also noted that they had notified the local authorities and residents of Zhambyl oblast of the coming storm beforehand. They said that the storm was caused by “synoptic processes superimposed on the physical-geographic features of the region”, i.e. the mountainous landscape.
“When the synoptic processes pass mountain ranges, they intensify, which causes a storm wind. In the period from 2008 to 2012 we have registered 235 cases of storm wind of up to 30 m/sec. 19 of them were registered in Zhambyl oblast. All this is typical for our country because of the sharply continental climate,” Director of HydroMetCenter of KazHydroMet Bayan Sazanova said.
A strong wind hit Zhambyl oblast on January 12. The disaster left the towns of Zhanatas and Karatau and several villages without electricity, water, heating, gas and communications. Nearby Taraz city was affected by storm as well: its power lines were damaged, roofs of many houses, hospitals, schools were ripped off, trees and road signs were scattered in the streets. The works on elimination of the consequences of the disaster are still in process.
