Hydrometeorological and agrometeorological information of 3 August, 2018
In the coming weekends, weather conditions will be determined by influence of atmospheric fronts and moist air masses from the Baltic. Hot weather is expected, intermittent rains with thunderstorms will be registered locally in the country.
At the beginning of the week (Monday-Tuesday, 6-7 August) northern part of Belarus will be influenced by moist air masses from the Baltic where intermittent rains with thunderstorms will be in several places. Precipitations are unlikely in an increased pressure area in southern Belarus. Because of the flow of cooler air from Scandinavia, temperature will decrease especially in northern parts of the country.
In the middle of the week, anticyclone from Western Europe will extend its influence to Belarus. It will bring dry and hot weather.
In the first decade of August, water level decrease will be observed on the rivers of the country.
As at 3, August, according to data of state hydrometeorological observation network, water levels exceed the marks of water discharge on the flood land on the Sozh near Slavgorod of Slavgorod district in Mogilev region and its river Besed near Svetilovichi village of Vetkovskiy district in Gomel region.
Unfavourable conditions for river transport are observed on the Zapadnaya Dvina near Vitebsk, on the Neman near Grodno and on the Dnieper near Mogilev. Water level is below marks that limit shipping here.
At the end of July – at the beginning of August as quantity of rains decreases and air temperature increases, agrometeorological conditions for after-rippening of grain crops and grain drying have improved. The farmers of the Republic increased harvest speed, Vitebsk and Mogilev regions have started mass harvest. According to recent data, moisture of harvesting grain decreased, amount of grain with conditioned moisture (12-14%) flowing to elevator increased. However, grain moisture is excessive (15-19%) in most of the observed fields, according to meteorological stations data – 21-29%.
Favourable conditions for harvesting of maize, root crops, vegetables demanding of heat and cultivated in open ground, for aftergrowing of herbs are forming. Because of hot weather at the beginning of August, conditions for growing of potato tubers deteriorated. According to recent data, average temperature of soil at depth of 10 cm is +23 +28С in most of the country which is much higher than optimal (optimal temperature for growing of potato tubers is +16 +19С)
Because of abundant rains in July, overmoisture of soil remains in some areas. Preconditions for appearance of disease excitants are set in the areas with excessive soil moistening, more intensive growth of weeds is observed. Frequent rains in July provoked formation and development of late blight on potato and tomato plantings.
In the coming days, expected intermittent rains should not influence harvesting. At the middle of next week, dry weather will let the farmers maintain high speed of harvesting.
