Climate change in the mountainous regions of the Republic of Tyva: The case of the Bay-Tayginsk district
The most considerable increase in the temperature of soil surface was observed in the cold period (1,5 °С, a 53,9% rise in temperature), the smallest in August (0,3 °С, 2,1 %), whereas, in May-June, the increase was negative (–1,3 °С, 27,1 %). Major increases in air temperature take ...
Hysteresis loops for a bulk ferromagnetic by Heisenberg model
... into account, explicit form is obtained by permutations group theory, the division paramagnetic/ferromagnetic is studied. The magnetization curves are built for a given set of parameters, such as exchange integral, number of closest neighbours and temperature. In a special range of the parameters a transition from unique solution of the resulting Heisenberg equation to multi-valued is observed. For this case exemplary hysteresis loops are built. The expression for Curie temperature allows ...
Chlorophyll «a» concentration in the South-Eastern Baltic Sea in summer 2018 (on satellite data)

The average concentration of chlorophyll "a" in the warm period of 2018 (May-August) was 3.8 mg/m3 while the average sea surface temperature was 17.7° С. The Maximum concentration of chlorophyll "a" (8.1 mg/m3) was recorded in May. However, the most massive development of phytoplankton occurred in July — the average monthly concentration of chlorophyll "a" ...
The dynamics of air temperature extrema as an indicator of climate warming in the Central Tuvan basin of the Tyva Republic
Climate warming results in an increase of air temperatures extrema. The dynamics of anomalies in air temperature absolute maxima are described through unusual biquadrate polynomials. The minimum peak was observed in 1989—1992, afterwards a steep increase followed. The authors examine the possibility ...
Development of a mathematical model for the process of rocket fuel bubbling with liquid nitrogen
To achieve an optimum temperature of rocket fuel, its negative temperature and the amount of its purification from impurities are necessary. For this purpose, a mathematical model of the temperature dependence inside the bubbler has been developed in this article.

The least squares method was used to find the empirical dependence of the heat nitrogen on the temperature. Third order polynomial approximation gives the average deviation from experimental data of less than 0.5 %. The paper also shows that with increase of the wall temperature of channel increases the required pressure at the inlet of the lance ...
About a role of vegetation of deserts of Central Asia in climate change
This article focuses on the temperature of various underlying surfaces (rubble-rock on hamadas, sand on the beds of temporary streams, plants) in the southern steppes of Mongolia. The authors present a comparative analysis of soil and plant temperature and address the issue of the ...
The characteristics of the energy spectrum of mixture ratio and air temperature in the troposphere of the Antarctic
This article analyses the characteristics of the energy spectrum of mixture ratio and air temperature in the troposphere of the Antarctic obtained by Fourier analysis. Selected peaks of spectral density of mixing ratio and air temperature monthly averages are interpreted as annual and semi-annual fluctuations. The spectral density of random ...

Shifts of adulterations as the result of seasonal horizontal convection under the shelf plate (numerical modeling)
... variations which delays an establishing of a seasonal water-exchange in shallows. Convective exchange flows within the entire shelf region in seasonal circle requires 4—7 weeks to reach a quasisteady state. Formation of a linear portion on the horizontal temperature profile can be used as an indicator of the approaching of the flow to the steady state. Flushing time for the shelf zone under steady-state condition is 30 days and is only slightly influenced by the slope length.
