ESTIMATE OF MAXIMAL VERTICAL VELOCITIES OF CONVECTION IN NATURAL WATERS WITH LAKE BAIKAL AS AN EXAMPLE

Abstract

In order to estimate the maximal vertical velocity of convection in natural waters, we propose a formula modified by multiplier 2 under the radical sign with the assumption that kinetic energy per mass unit does not exceed potential energy. These two formulas agree well with estimates for vertical velocities of convection based on another method for the case of mixing of the cold Labrador Current and warm Gulf Stream. In the case of Lake Baikal, we consider a real range of water density variation depending on the degree of cabbaling of natural waters due to temperature and suspended matter content with the detailed analysis of anomalous variation near the temperature of the maximal water density.
