“Will a two-century record of precipitation in Moscow be broken?” reads the headline.
If on Sunday more than 40 mm of precipitation falls, then the total amount of May rainfall will exceed 140 mm. Such a record was set by nature 199 years ago, in 1821. At the moment, in May, 103 mm had already fallen. And if the cyclone is reborn on the last day of the month, then wait for a new record.
However, a different headline – “Facts vs hype: what is the same with the record of precipitation in Moscow?” – thinks the record may be more “youthful.”
‘Today I came across the headline “May in Moscow could break the record for rainfall in 199 years,”’ the second article begins.
This article insists that the main weather station for determining weather records, the VDNKh weather station, generally began observing in 1939. It was at this station in May 1976 that the maximum monthly rainfall was recorded – 143.3 mm.
However, the article agrees, this almost “youthful” record in the last day of May is likely to be broken. To do this, you need only 40 mm of precipitation (with an average May norm of 51 mm).
So…I don’t know which story is true. But if that weather station was established in 1939, it would still mean that it will be the most May rainfall since 1939, not exactly a “youthful” record.
And now a third article claims “May 2020 is a record for rainfall!”
For the first 29 days of May in Moscow, at VDNKh, 102.9 mm of precipitation fell. And the night of May 30 was with heavy rain , another 23 mm fell on VDNH.
The last day of May in the capital will be very rainy. For a day on May 31, the amount of precipitation may exceed the record amount, 22.5 mm, which was observed on May 31, 1977.
As a result, the monthly total precipitation will exceed 135 mm, which will be a new monthly record!
While the record for the monthly total precipitation is 131.7 mm and belongs to the distant 1933.
In the current century, the wettest May was in 2015 with a rainfall of 119.4 mm. / meteonovosti.ru /
So which is it? Most May rainfall since 1933? Most May rainfall since 1939? Most May rainfall since 1821?
Whatever it is, that record is older than most of my readers.
Whatever it is, I think Martin Siebert sums it up nicely:
“When there are more cosmic rays,” says Martin, “they help create more microscopic cloud cores, which in turn form more clouds, which reflect more solar radiation back into space, making the Earth cooler than it normally can be.”
“More cosmic rays … more clouds … more rain … less heat means…Global Warming!?”
