Monthly average temperatures, precipitation, and snowfall data for each episode was compiled for Fort Wayne and South Bend. Multiple locations were found.
When there is relatively high pressure over the northern polar region and relatively low pressure in the middle latitudes, the AO is considered to be in a negative phase. Precipitation was also below normal for both December 1. The average temperature was 5.
I suspect that trees in regions with shallow and ephemeral snowpacks will benefit from warmer winters as well since they most likely deal with substantial fine root mortality every year. Meteorologist Colleen Coyle says, "that would be an amazing thing, a breakthrough in science if you could say a year from now what the weather is going to be like. A more detailed explanation of these maps can be found at here.
Story compiled by: Snowfall was 4. Siovhan Bolton.
However, La Nina systems are usually very strong and moisture rich and tend to overcome the negative precipitation anomalies associated with the negative AO in our area. If so, what would this mean for the trees and forests? The average temperature was 4 degrees below normal for December, 2.
Colin Beier indicates that yellow-cedar is particularly susceptible to decline in the Pacific Northwest due to a lack of snow and freeze-thaw cycles.
Subsequent independent research supports this concept.
However, if the AO and NAO are in a positive phase when a storm system develops, there could be less cold air and potentially more liquid precipitation. Cold and snowy, above average snow and significantly low rain.
These effects are usually strongest during the winter months when the jet stream is strongest over the United States.
Additional information on the AO can be found at http: I saw some red maple trees in bloom on February 5th. A couple of things amazed me about this study. Before anyone freaks out -- our Verify team looked into just how accurate the almanac really is.
Almost all of the radial growth of the six species I studied would benefit from warmer temperatures.
