"What are the climate characteristics of Kazakhstan?"
Depends on the region, where I am in Ust-Kamenogorsk (East Kazakhstan on the border of Siberia, Mongolia and China) ... Maximum temperature +40C, minimum temperature -55C.
Wind strengths can range from calm up to 30-40 metres/second (100-150km/hr).
Inside apartments, shops, most city buildings, the centralised heating is turned on at the beginning of October and turned off again in late April, so you will be warm during winter if you remain inside.
You will need to practise walking on ice if you go outside and have good clothing to deal with the extreme cold. If you have to walk to your bus stop, make sure you have good insulated gloves and insulating socks and shoes, a ushanka is useful too (although you lose more heat from your hands than you do from your head) ... I find I can survive the cold without the ushanka standing around waiting for a bus, but need good gloves and socks below about -20C.
The main public transport is by bus or in the centre of the city, trams, these are heated and you are able to survive the cold in them. The older (10-20 years) secondhand buses that were bought from the Scandinavian countries are best suited to the Ust-Kamenogorsk climate with double glazing, industrial level heating for Arctic winters, good seating and good drive trains (they still have their original destination boards up, Stockholm, Uppsala, Malmö, Linköping).
The newer buses from China and Korea are not up to the job (no double glazing, not good heating systems, unreliable ... often breaking down, seating only for very small people or children, forget trying to sit properly if you are bigger than about 170cm), but hey, perhaps someone got them cheaply ...
Upside, there are no insects in winter, they cannot survive.
In summer, there is generally no air-conditioning ... and insects are out and about, mosquitoes and ticks, bear in mind too, that the East Kazakhstan region also has marmots, a vector carrier of Y. pestis ... and recently there have been a number of anthrax infections.
