Mean winter temperature has warmed faster than global average, by about 2.1 °C (3.8 °F).(1). While the whole state has seen a steady decline in snowfall, snow loss is particularly prominent in southern New Hampshire. Between 1950 and 2003, annual snowfall in the city of Berlin in northern NH decreased by 43 cm (17 inches)(1).
Insect outbreaks also represent an increasingly significant threat. Historically, temperatures have been low enough in the wintertime to control insect populations, but under global warming, many insects are surviving and reproducing during the winter months, causing severe damage to forests across the North American boreal.
The meridional (interhemispheric) mode demonstrates seasonal changes, arriving to a maximum during the boreal spring, on and north of the equator. The seasonal changes in surface wind forcing, which are closely linked to the seasonal displacement of the ITCZ, incite a response on the ocean surface, affecting current systems in the tropical Atlantic as well as the slope of the underlying ...
How does winter impact the lakes. In the Great Lakes, water temperatures are roughly the same temperature from the surface to the bottom of the lake in spring and fall. During winter and summer ...
This winter was originally thought to be dominated by the La Niña phenomenon. But now, the Climate Prediction Center believes it will be a "weak and a short duration La Niña" – if it appears ...
The amount of snow falls in New Hampshire is predicted to be slightly lower than normal - 1 to 1.5% below average, according to the Old Farmer's Almanac, which added that "the snowiest periods ...
The boreal forest/taiga supports a relatively small variety of highly specialized and adapted animals, due to the harshness of the climate. Canada's boreal forest includes 85 species of mammals, 130 species of fish, and an estimated 32,000 species of insects. [37] Insects play a critical role as pollinators, decomposers, and as a part of the ...
The subarctic climate (also called subpolar climate, or boreal climate) is a continental climate with long, cold (often very cold) winters, and short, warm to cool summers. It is found on large landmasses, often away from the moderating effects of an ocean, generally at latitudes from 50°N to 70°N, poleward of the humid continental climates .
