Аннотация:Phenomenon of urban heat islands (UHI) was researched by many authors of scientific community. More investigators
were focused on heat island of tropical city. (for example: Tropical urban heat islands: climate, buildings
and greenery / Nyuk HienWong and Yu Chen. – London, 2009; 259 p.) However dynamics UHI in arctic, subarctic
and sharp continental climates is poorly investigated. This situation is due to the fact that there isn’t large cities in
Europe and Northern America within that climate type. In this paper we investigate long-term, seasonal and diurnal
dynamics UHI intensity for more than 20 cities of the Russian Federation (large than 100 000 population). Was
calculated and analyzed changes UHI intensity within days and year. Also was detailed reviewed extreme values
UHI and was discussed their relation with synoptic situations.
In that investigation data created by regular state meteorological observation ROSHYDROMET network was used.
For every city we selected couple of stations: one located into city in high and midrise buildings area (including
extensive lowrise and high-energy industrial - LCZ classification) and second one located in rural site (sparsely
built or open-set and lightweight lowrise according LCZ classification). Also couples of stations must be close by
distance (less than 100 km) and altitude. For selection operation was constructed spatial database in ESRI ArcGIS
Desktop environmental.
Advantage investigation UHI of Russian city is diversity of climate condition. Selected cities locate within territory
from 40N to 70N latitude and from 20E to 160E. That fact allows research UHI phenomenon in space term. Were
detected intensity UHI patterns depends on geographical location of the city.
