The Answer to the Comments by Yu. D. Resnyanskii to the Papers by L. Kh. Ingel’ and A. A. Makosko

The critical comments to the publications by the authors ofthe present paper that were given in [10] (the publications deal with the possible effects of gravity field inhomogeneities in the atmosphere and ocean) are discussed. In the authors' opinion, some remarks are groundless. At the same time, the authors agree with one of the important remarks that the results of their paper concerning studies of the ocean disturbances are to be reconsidered.     

Distribution of methane content and methane fluxes in the Sea of Japan,Sea of Okhotsk,and near-Kuril Pacific

The spatial distribution of methane content and methane fluxes in the water in the north-western part of the Sea of Japan, in the Kuril basin of the Sea of Okhotsk, and in the near-Kuril part of the Pacific Ocean is studied using the data of marine research expeditions in 2005, 2010, and 2011. The studies revealed the significant variability of the methane flux depending on the source presence and on the sea surface conditions. The high emission of methane from water to the atmosphere is registered in the areas where its concentration exceeds the equilibrium values with the atmosphere. The use of the model of computation of the fields of currents and contaminant transport for the investigated water area enabled explaining the formation of the high concentration of methane in the center of vortices in the zones of sea water convergence in the water areas under study.     

镇江市酸雨特征及影响因素分析

利用2008年1月至2012年12月镇江市酸雨观测资料,详细分析了镇江市酸雨强度和发生频率的年、季、月变化特征,并对影响酸雨发生的气象因素进行了分析。结果表明:镇江市酸雨年、季、月平均pH值均较低,酸雨强度均较大,春季和秋季是酸雨的高发季节。由降水量、风向、逆温及外来污染源垂直输送等气象要素对镇江市酸雨的影响可知,镇江市强酸雨的发生频率和占总降水量的比例均较高;NE、SE和E这3个风向对镇江地区酸雨的总贡献率超过50.0%;华北、华东、湖南和湖北地区是镇江市酸雨发生的可能外来污染源;低层(925hPa及以下高度)出现逆温时,更易出现酸雨,且逆温层厚度均较深厚;逆温温差的强度与酸雨强度有一定的关系,即温差越大,pH值越低,酸雨强度越大。     

防雷箱残压“二次感应”的研究试验与仿真

防雷箱广泛应用在各类低压配电系统的雷电防护中,为研究防雷箱在8/20μs冲击电流作用下常出现"二次感应"的现象,基于Haefely DIAS 733测试系统通过大量试验,结合电磁感应理论对感应电压进行计算,并利用PSPICE建立感应回路。结果表明:1防雷箱内部平行布线且输入输出同端口时,"二次感应"电压幅值服从电磁感应定律,且可进行较精确计算。2采用双绞线布线、地线与输出线非平行、输入与输出线异端口且与地线非平行3种方法可有效地降低因电磁感应而增加的残压,从而获得较低的输出残压。3试验表明,当内部采用输入与输出线异端口且与地线非平行的综合布线方案后,效果最明显,在60kA冲击电流下,相对未改进的防雷箱,采样点残压下降约45%。     

基于LLS的雷电流波头时间分布特征

利用湖北省2007—2013年雷电定位系统(Lightning Location System,LLS)监测的雷电流相关参数资料,采用数理统计方法,对雷电流波头时间的年、季、月、日变化以及累积概率和概率密度分布进行了统计分析。结果表明,正闪电平均波头时间为4.8μs,负闪和总闪电为3.6μs;一年中,正闪电7月波头时间最短,月变化特征大致呈"V"形;负闪和总闪电5—7月波头时间比其他月份短,月变化特征大致呈"U"形。正闪电波头时间季节、日变化明显,负闪和总闪电季节、日变化不明显。波头时间小于等于10μs时,正闪、负闪和总闪电的波头时间累积概率分别为95.5%、99.7%和99.6%,总闪电95%的波头时间大于1.5μs,50%的大于3.1μs,5%的大于6.0μs。波头时间在2~3μs时,正闪、负闪和总闪电的概率密度最大。气温较低月份,波头时间相对较长,反之,波头时间相对较短,其原因可能与雷电流幅值大小有关,具体原因有待进一步研究。     

Long-term estimates of parameters of the vertical distribution of cloud layers from atmospheric radiosounding data

Based on the global aerological dataset and on the method for determination of the boundaries and amount of cloudiness using the profiles of temperature and humidity obtained from the atmospheric radiosounding data [23], the estimates are computed for the parameters of atmospheric temperature- humidity separation into cloud and intercloud layers from the surface to the height of 10 km. The base and top of cloud layers and their total thickness and frequency are selected as layering parameters. The computations are based on the data for the observational period of 1964-1998. To specify the spatiotemporal features of atmospheric layering, long-term geographic distributions of mean values and standard deviations of the mentioned parameters are constructed for January and July, and the amplitude of their variations is determined.     

Diurnal variations of temperature as a cause of periodic variations of high-frequency geoacoustic emission

Investigated is the periodic component of geoacoustic emission within the frequency band from 2.0 to 6.5 kHz registered by the piezoceramic hydrophone installed near the bottom of Lake Mikizha in the Kamchatka Peninsula. It is revealed that the variation period is 24 hours and the maximum variation is observed in summer, when the average daily air temperature is above 10°C. In that period the close connection is revealed between the series of air temperature and geoacoustic emission. Taking into account the similar results of measurements of the ground surface slope at the observation site, the most probable reason for the diurnal variations of high-frequency geoacoustic emission is the deformation of near-surface sedimentary rocks caused by diurnal variations of temperature.     

Spatiotemporal variations in climate moisture indices in Georgia under global warming

Using observational data from 50 weather stations in Georgia for the period of 1936-2013, the following climate indices of moisture regime are studied: maximum 1-day precipitation, maximum 5-day precipitation, the simple daily intensity index, the number of days with precipitation equal to not less than 10, 20, and 50 mm, number of consecutive wet and dry days. Geoinformation maps of the spatial structure are plotted, and the dynamics of these indices is studied for the period of global warming. Expected changes in the moisture regime in different physiographic regions in Georgia are assessed.     

Long-term projection of main parameters of regional climate till the year 3000

The methods are considered to solve the problem of secure isolation of radioactive waste containing long-lived products of nuclear fuel processing with a half-life of tens of thousands years (plutonium etc.). The methodology of long-term projection of average annual surface air temperature and total precipitation is proposed. Taking into account the possible scenarios of the development of the global socioeconomic system, variations due to the anthropogenic impact in average annual temperature at the Northern Hemisphere mid-latitudes for the period till 2300 are estimated. Based on paleoclimatic data, projections of natural trends in global average annual temperature and total precipitation till the year 3000 are developed. Taking into account the anthropogenic component, the projective ranges of these climatic parameters in the Vyatka River basin in 2100-3000 are evaluated.     

Verification of the multi-chamber model of radioactivity migration in reservoirs

A multi-chamber model of radioactivity migration in reservoirs was developed. It describes transport of radioactive substances in water and in bed sediments taking into account sorbtion of radionuclides on suspended particles. The model provides higher resolution than simplified chamber models do. At the same time, unlike complex two- or three-dimensional dynamic models, it does not require hard-to-obtain data such as detailed data on bathymetry, currents and winds. The model was included into the Sybilla program code that was developed in the framework of the Rosatom project called PRORYV. The model was verified against the observed data on the contamination of the Kiev Reservoir with ¹³⁷Cs in 1986.
