The article identified and studied meteorological station at which the maximum observed incidence of AEs category ice deposits on the territory of Ukraine for months and some cold months of the warm period of the year for a number of periods: climatological standard norms 1961-1990 biennium., And 1991-2000, 2001- 2010 and 2011-2015. It was established that in all regions of Ukraine during the period are meteorological stations with the highest number of cases of ice deposits category AEs that are repeated in most of the studied months. This indicates a resistance centers of deposits in time and space and show no chance of occurrence of these deposits. In the months warm period was not always meteorological stations of the maximum number of cases of ice deposits category of AEs consistent with other researched for months. In most areas studied during 4 periods set a number of meteorological stations with the maximum number of cases of ice deposits category AEs that are repeated from one period to another. The ferry is such that were recorded only in one of those periods and is not present in others. The study produced the following results: - For all 4 study period in most regions of Ukraine is a meteorological station on which there is the highest incidence of AEs category deposition of ice, that they form centers of deposits. - Most of the study period for the vast number of areas often one and the same center ice deposits category AEs observed in the months of cold period of the year - January, February, November, December, and sometimes March. However, in some areas they may be repeated in the months warm season (April to October). - The standard climatological period 1961-1990 standards. Most stable center ice deposits in the category of AEs observed areas: Rivne, Ivano-Frankivsk, Chernivtsi, Zakarpattia, Poltava, Zaporozhye, Lugansk, Donetsk, Mykolaiv, Kherson and Crimea. In Kyiv and Kirovohrad regions revealed the instability of center ice deposits category AEs in this period, considering all months of cold season and some warm months. - In 2000-2001 In most regions established centers category AEs ice deposits found that the stability of its positioning from month to month, namely Chernihiv, Sumy, Zakarpattia, Rivne, Lviv, Khmelnytsky, Poltava, Kharkiv, Luhansk, Kirovohrad, Dnipropetrovsk, Donetsk, Odessa, Zaporozhye and Kherson. With that, the most stable ice deposits were centers category of AEs of areas: Zakarpattia, Ternopil, Luhansk, Donetsk and Zaporizhia. For areas such as Ivano-Frankivsk, Ternopil, Chernivtsi, Zhytomyr, Kyiv, Vinnitsa, Mykolayiv and Crimea, sustainable centers of deposits is not established, though some of them, Zhytomyr, Kyiv, Mykolaiv, Kherson and Crimea establishes separate centers of deposits in which there are certain prerequisites for their probable sustainability. - 2001-2010. Resilience center ice deposits category of AEs was found in the areas of: Zakarpattya, Ivano-Frankivsk, Chernivtsi, Chernihiv, Poltava, Kharkiv, Luhansk, Donetsk, Dnipropetrovsk, Odessa, Zaporozhye. The most resistant were centers of such deposits in the areas: Zakarpattia, Ivano-Frankivsk, Poltava, Lugansk. Volatility center ice deposits category of AEs found in most regions: Volyn, Rivne, Sumy, Zhytomyr, Kyiv, Lviv, Khmelnytsky, Ternopil, Cherkasy, Vinnytsia, Kirovohrad, Mykolaiv, Kherson and Crimea. - During 2001-2015. In Zakarpattia, Rivne, Lviv, Ternopil, Ivano-Frankivsk, Luhansk, Kirovohrad, Dnipropetrovsk and Odessa regions were found stable ice deposits Centers category AEs not resistance centers ice deposits category AEs were installed in areas - Chernivtsi , Khmelnytsky, Zhytomyr, Kyiv, Sumy, Poltava, Kharkiv, Cherkassy, Vinnitsa, Donetsk, Zaporizhzhia and Crimea. However, in areas such as Chernivtsi, Poltava, Kharkiv, Poltava, Vinnitsa, Donetsk, Nikolaev was revealed station with the highest number of cases of ice deposits category AEs that further potential to be sustainable centers of deposits. - In general for the studied periods (1961-1990, 1991-2000, 2001-2010, 2011-2015.) Found that plants have the maximum number of cases of ice deposits category of AEs mostly repeated in periods of not less than 2 s of them, particularly including the base period. Some of these stations are even more stability and areavailable in more study period 3, or even all 4 periods: Play, Rivne, Chernivtsi, White Church, Fastow, Poltava, Kropivnitskiy, Volyn, Svitlovodsk, Sinelnikovo, Gift 'yivka, Debaltseve, Lyubashevka Ascania Nova, lower Sirogozy. - It was found that most of the stations with the maximum number of cases of categories AEs ice deposits that often repeated in the entire study period observed in Kharkiv, Vinnytsia, Kirovohrad and Crimea.
