This November, to a greater extent in the territory of Ukraine and the ETR, and to an even greater extent in the south of Ukraine, late-spring temperatures have been maintained for at least two weeks without a day. In the south of Mykolaiv, Kherson region Tmax. since the beginning of November, it has fluctuated within +17C +25C, morning temperatures do not fall below 10C, and for three consecutive days, on November 9, 10 and 11, the average daily temperatures were around +16 +19C, which is typical for the beginning of June.
According to the latest data from climate models, this anomaly in the south of Ukraine will last until Thursday next week, but new heat flows are not excluded. The nature of the phenomenon consists in a powerful meridian removal of North African heat by a series of Atlantic cyclones with the beginning of active western transfer from the end of October.

Napimer for Kherson Region Tan at the moment is approx. +8C, Tanmax +13.2 S

Interseno, who observes what anomalies in the activity of insects and other animals? In the south of the Mykolaiv region, minor anomalies are observed so far, such as the preservation of a certain number of erectoptera, some lepidoptera, mainly jaundice. Ground insects and spiders are regularly active.
However, today in the steppe I heard the first "alarm signals" - field crickets began to sing. During the search for soil for the hatching of straight-winged birds, I did not find anything. Plants are also in no hurry to wake up, but the peculiarity of the situation is that in October there were already frosts, and the current warmth can be regarded as a wake-up call.
Since yesterday, I've also noticed spring bird songs and frog concerts in the ponds.

crocea is even interesting in our season, they don't fly in every year, but here in November... well, rapae puzzled us, what kind of generation does it turn out to be - 4th, 5th ? )

The turnip, crocea, and some other species do not have generations as such. These species breed continuously, i.e. during the season they occur simultaneously in all four phases of development and adults fly without interruptions. Thus, by the end of the season, the crocea that flew into your region managed to breed. And in the Crimea, for example, they breed until they stop, in early December I met eggs, caterpillars, and imagos.
Considering that in Crimea, crocea is released in the middle (beginning?)of the year. If the development cycle lasts about 30 days, then the species can go through about nine full development cycles per season.

Today I saw the flower of chistyak Ficaria verna (see the photo in the reports) - but this is a spring ephemeroid! Buttercups also bloomed, but all this is isolated. On insects-nothing absolutely supernatural (late summer dates in the Kharkiv region are blocked for V. atalanta, P. c-album, S. striolatum, but this is normal: the weather allowed; in general, these species are always active in the fall "to the very stop").

Wow, it turned

out (spamfilter, damn it)

Yes, I still saw a blooming bruise, buttercups are blooming, dandelions, surepka, some other plants, but all this that I saw-these are isolated cases and in principle not unusual. But chistyak is already interseno, I was looking through the ravines for vegetation of gymnosperm, chistyak, primrose, but I didn't notice anything. As for the photoperiod-this is a complex philosophical question - how will the animal understand that there is a negative dynamics of insolation now, if it does not see

it, because many pupae lie in the ground, plant seeds, resting underground parts, all this can germinate, and when it understands that something is wrong, it will be too late.
Well, what I saw today, since I tracked down a singing cricket-that's something, ktstai he was the only one so far. It's like in the song about the bonfire, when "the crank did everything wrong" and his song is now spreading across the steppe.
Plants can be held back by drought, we have a soil drought, the soil is dry up to 15 cm, although there are fogs in the morning. And there are still a minimum of four days of anomalies ahead, so there may be more singing crickets

that is, imagos are not fastidious to the cold, and preimaginals are the opposite? or why then in our conditions crocea can not overwinter?

I did not mean frosts, but cold (small frosts?), i.e. caterpillars continue to feed, pupate, and do not leave for the winter. Either not everyone leaves. When warming, fresh imagos can come out.
I don't know about wintering grounds. We have winter drops to -10 ... 13 are quite common, -20 also occasionally happens. In the mountains and below. They probably spend the winter here only in some localities with a warm microclimate, because there are not many rabbits in the spring.

I haven't seen anything about spring flowers yet. Last year, by the way, November (in Crimea) was about as warm. I even went to the beach to sunbathe.

Last year in the south of Ukraine, too, in November there was a small positive anomaly, but more than modest, in Kherson the Tan was only +3C, but in the Crimea the anomaly was even less pronounced, here in Simferopol http://pogoda.ru.net/monitor.php?id=33946&month=11&year=2009 : Tan +2C-this is considered a variant of the new norm. This year, by the way, the anomaly in the southern Crimea is somewhat less than in the rest of Ukraine, as the norms are already high there. in addition, at the beginning of November there were severe frosts, strong enough for us to freeze out almost all the remains of insects.

Tonight I was returning from work and heard trills from the poplars, probably some grasshoppers still survived, and cheered up

According to the latest updates, T will be above +10C in the south of Ukraine until November 25, but then the option is not excluded, which in the picture

is of course the "tail" of the model forecast, and everything will probably change several more times, but in principle something like this is possible at the beginning of December

In Yaroslavl, the heat lasted until November 16 inclusive. Despite the screams of journalists about abnormal natural phenomena outside the city, everything was as usual. I went to the forest on November 12 - only spiders were active... The rest were sitting in the winter quarters. In the city, with its artificial lighting (and the shift in the length of the light day), lawns were green, some of them blooming autumn plants - alyssum, bluebells, odorless chamomile. The jackdaws had a bath day. The beetles came out, too. On the light walls for a couple of days, I collected a wrinkle beetle (Helophorus), a knotweed (Ptinus) and a leaf block from the genus Phyllotreta, and then I found a fringed swimmer - apparently flying and shied against a wall or roof (and repelled the elytra).

Well, November is coming to an end, and these days the "summer"has already ended in the south of Ukraine. However, the day before yesterday I saw blooming goatbeards, an abundance of blooming and already fruiting dandelions, and bees on the flowers, and not only honeybees!

However, unfortunately, an icy inferno is coming to the center of the ETR, approximately as in the forecast of the State Fiscal Service of November 15. So the trends were seen correctly, but so far it seems that it is expected that on December 1, isotherm-20C will not enter the territory of Ukraine, but will stop almost nearby. At the same time, for Europe, the option is currently more severe - the isotherm (in rings)- 10C should cover the entire zap. Europe, so to speak, up to the very Netherlands.

And after December 1, at least two or three days of summer are expected in the south of Ukraine(up to 18C near the World Cup coast). Summer is also expected on November 29, but with thunderstorms and rain. So there will probably be more opportunities to wander around

Not quite on the topic, of course, since it's already December, but nevertheless! Residents of the south of Ukraine who love warm spring days in December - there is good news

All the power of the Atlantic and the warmth of Africa will be thrown against the freezing winter from December 20, and as a result, it is possible to establish temperature regimes up to Tmax. +15C in the south and up to +20C in the Crimea until January 1, and possibly further. Positive anomalies can have two-digit values. If you are lucky, the +10C isotherm can reach the Donetsk-Kryvyi Rih line with no snow and already a good warm-up.

For sure, tarantula burrows will open, various animals will infest, maybe something will bloom. Interseno is that it is possible that many days will be clear and quiet. So flying is also possible at night.

Another announcement of the upcoming cold snap - after the current cold snap, which was relatively not very intense and the next three-day warming from Tuesday to Thursday of this week, which will manifest mainly in the east, where temperatures can be up to +23C, from Friday, October 14, a very strong cold snap will begin, at the peak of which GFS expects frosts up to-5C in almost the entire territory of Ukraine, frosts will begin at night on Sunday and the maximum cooling may be on Tuesday, October 18. After that, a relatively strong warming will begin, up to +20C in the southern regions.
This is a preliminary review of the SFS forecasts...

And after the cold snap that we had, almost all the grasshoppers, decticuses, tettigonias disappeared, but there were almost as many locusts left.
