Fish are more stressed and susceptible to disease when exposed to a higher or lower than
usual temperature for an extended period of time, or when exposed to a temperature change greater than 2 to 3 degrees within a 24 - hour period.
Meanwhile, on the cut - off high's eastern side, winds heading south drove cold air from the Arctic Ocean toward Greenland's southern tip, bringing the lower than
usual temperatures there.
Map of air temperature anomalies for December 2009, at the 925 millibar level (roughly 1,000 meters [3,000 feet] above the surface) for the region north of 30 degrees N, shows warmer than
usual temperatures over the Arctic Ocean and cooler than normal temperatures over central Eurasia, the United States and southwestern Canada.
To some extent, this is down to a stronger than
usual temperature contrast, with cooler - than - average water in the North Atlantic to the east of Newfoundland and warmer - than - average water to the south.
The cooler - than -
usual temperatures are represented by the big blue blob on the world map below (that's Florida peeking out at the lower right of the blob), provided by atmospheric scientist Jennifer Francis of Rutgers University, New Brunswick, using NOAA data.
One, again, is changing wind patterns; in July, NSIDC noted that a strong - low pressure pattern over the Amundsen Sea during June had brought lower - than -
usual temperatures.
If you plan to visit Pikes Peak or other summits during your trip, check
the usual temperature for the time of year you are visiting.
Here is what I understand of what they are saying: — In recent years the Arctic has been experiencing much warmer than
usual temperatures and unusual loss in sea ice.
One promising area of research are corals that are already living in warmer - than -
usual temperatures:
The difference was due to much - warmer - than -
usual temperatures and the fingerprint of global warming contributing to those temperatures has been formally identified.
One word: AmeriFlux (weather stations that measure the various energy IR flux terms — beyond
the usual temperature, wind speed and humidity)
Despite the colder than
usual temperatures this year, the show was well attended by eager riders looking forward to getting their bikes out for the season.
