Spring-like temperatures all over Germany

While many people in the USA are struggling with extreme cold, there are mild, almost spring-like temperatures throughout Germany. As a result, not only for allergy sufferers does the “pollen season” start much earlier than usual, the first birds also start looking for nesting sites.

USA tremble at temperatures as low as -54.5 degrees Celsius Large parts of the USA continue to suffer from arctic cold, according to "tagesschau.de" near Duluth (state of Minnesota) on Lake Superior the lowest value has meanwhile been reached at -54, 5 degrees Celsius perceived temperature including wind factor measured, the metropolis Chicago is currently freezing at minus 25 degrees. In Germany, on the other hand, the winter is still not in sight. Instead, “the average temperature in Germany in December was 2.7 degrees above the long-term average. In January, the positive deviation is even over 5 degrees if you only consider the first 7 days, ”explains Dipl.-Met. Marcus Beyer from the German Weather Service (DWD).

Mild winter not only has advantages Instead of a winter atmosphere with snow and freezing people in thick coats, a spring mood is currently emerging in Germany, with mild temperatures up to 15 degrees Celsius, the first twittering of birds and blooming flowers in the front gardens. According to the meteorologists, "spring" should continue until the end of the week - then the temperatures would probably drop again somewhat. But the mild winter doesn't just have advantages. Allergy sufferers, for example, have to fight pollen much earlier than usual, because in some parts of the country there is already hazel pollen in the air. According to information from the German Meteorological Service (DWD), North Rhine-Westphalia, the Saarland and the Frankfurt area in particular are currently "slightly polluted", but pollution in Lower Saxony, East Westphalia, Saxony-Anhalt and North Hesse cannot be ruled out these days either.

Warm temperatures disturb the bio rhythm of the animals However, the mild winter weather does not only affect humans - the warm temperatures disrupt the usual bio rhythm especially for the animals and ensure that certain processes start much earlier than usual: “In This year the birds started singing around Christmas and seem to be more active than usual at the moment, "Lars Lachmann from the Naturschutzbund Deutschland (NABU) told the AFP news agency. This would concern, for example, great tits and blue tits, which are now in early January In addition, the latest bird count would have shown that fewer birds than in gardens would be looking for food, as the warm weather in "free nature" means that there is still enough food to be found: "Overall there are slightly fewer birds in the gardens and parks than in the previous year, an average of exactly 40 per observation gsort and thus eight percent less, ”says the bird protection expert.

Ticks active much earlier than usual. Therefore, a sudden change in the weather would not be a problem for the animals, because then the birds would either look for food in the cities or head south. The current weather is also ideal for ticks, according to Christine Klaus from the “National Reference Laboratory for Tick-Communicable Diseases” in Jena. As the little spider animals start to become active at around six degrees Celsius, the tick season does not start as usual at the end of February / beginning of March, but much earlier. But that would by no means mean tick plague, the expert told the "AFP", because "when it gets crunchy cold, the ticks retreat again."

Late frosts in spring damage young shoots. However, the mild temperatures could have a more problematic effect on agriculture. As the agricultural meteorologist Franz-Josef Löpmeier from the DWD told AFP, later in the spring, frost could damage the young shoots if the winter seeds grew too early in the currently warm temperatures. It would be particularly difficult if the temperatures then dropped below minus ten degrees and there was no snow at the same time - the plants were not hardened enough to survive this without damage.

Strong cold air flow early next week? But such a severe change in weather is currently not in sight, according to the meteorologists from the German Weather Service. According to Dipl.-Met. Marcus Beyer from DWD currently has “model results” that would assume a strong cold air flow at the beginning of next week, “but other solutions leave the cold air over Eastern Europe or only provide a short graze”, the weather expert continues.
