In Greenland, and particularly the northeast corner-may was colder than what we normally experience in these parts. Blame can greatly kicks on the polar front location.
Climatologist John Cappelen have looked the numbers through. In the Danish port have DMI registered the coldest may since measurements began back in 1949.
"Danmarks havn ends with record low-11.1 ° c-degree frost as mean temperature. It should be hung up on that normal are calculated in the period between 1961 and 1990, at-6.5 ° c, "says John Cappelen and continues his cold history:
"In daneborg, where Sirius patrol belongs, it was also a cold month with a mean temperature of-9.0 ° c. Thus, it was the second coldest may registered here since 1958. "

Due to the polar front
It was not only in the Northeast, to the cold had taken over. In the rest of Greenland was also colder than normal. The cause of the cold weather can greatly be found in polar front location.
The polar front separates the cold air mass over the North Pole with the warmer air mass above the equator. It is not stationary, but the waves back and forth. In may it was mainly South of Greenland, and thereby has been in Greenland the cold air mass with high air pressure.
Often moving low pressure up along the coasts of Greenland, and these low pressure acts as heat pumps. The cold, however, has kept the cyclones bastante at a distance.
Not only in Greenland was may a cold pleasure. Also in Denmark we saw for the first time in 22 months that a month was colder than climate normal. Here was even the second wettest may since 1874.
