Abstract

The paper shows the changes in the dates (complete freeze-up, ±5 days/°C and complete ice clearance, ±3 days/°C) of the ice regime in Lake Onego depending on changes in average air temperature within the preceding two-month periods (autumn and spring). The regression equations for their calculation based on previous three- and four-month periods according to the 2000-2018 data are also provided. Indicative dates of ice regime based on accumulated air temperatures within the ice period of Lake Onego were also established (early formation of ice phenomena, complete freeze-up phase, beginning of the break-up phase and complete ice clearance). Together with the data on expected air temperature above the lake’s surface, these dependencies enable us to predict the indicative dates of the ice regime.

基于地面气温的奥涅戈湖冰况指示性日期的变化

本文显示了奥涅戈湖冰况的日期变化(完全冻结，±5天/°C和完全解冻，±3天/°C)取决于前两个月(秋季和春季)平均气温的变化。并根据2000-2018年的数据，给出了基于前三个月和四个月的回归方程。根据Onego湖冰期内的累积气温，建立了冰况的指示性日期(冰现象的早期形成，完全冻结阶段，开始破裂阶段和完全冰清除)。再加上湖表面以上的预期气温数据，这些相关性使我们能够预测冰态的指示性日期。

期刊介绍： Advances in Oceanography and Limnology was born in 2010 from the 35 years old Proceedings of the national congress of the Italian Association of Oceanology and Limnology. The AIOL Journal was funded as an interdisciplinary journal embracing both fundamental and applied Oceanographic and Limnological research, with focus on both single and multiple disciplines. Currently, two regular issues of the journal are published each year. In addition, Special Issues that focus on topics that are timely and of interest to a significant number of Limnologists and Oceanographers are also published. The journal, which is intended as an official publication of the AIOL, is also published in association with the EFFS (European Federation for Freshwater Sciences), which aims and objectives are directed towards the promotion of freshwater sciences throughout Europe. Starting from the 2015 issue, the AIOL Journal is published as an Open Access, peer-reviewed journal. Space is given to regular articles, review, short notes and opinion paper
