Samples from selected countries were assumed to represent one of the three discrete geographic regions: high-latitude area (>50[degrees] N), mid-latitude
area (<50[degrees] N), and Oceania (Australia and New Zealand).
Westerlies are running on their normal track of mid-latitude
, an official of Met office told reporter.
Although the causes of AA are not well understood, especially with regard to the relative role of oceanic circulation, it remains a withstanding problem to explain a link between AA and anomalous mid-latitude
wintertime circulation patterns.
The model represents synoptic scale mid-latitude
atmospheric dynamics based on the quasigeostrophic approximation, which assumes hydrostatic balance and allows only small departures from the geostrophic balance.
Additionally, during the night, frequencies reach a minimum of approximately 60deg latitude north and south of the geomagnetic equator, and this is named the mid-latitude
In Geneva for example, where dawn does take place, the daily fasting time nowadays is 18.5 hours; in mid-latitude
cities like Rome and New York, it exceeds 17 hours; in places like Stockholm, the fasting period is more than 20 hours, if one takes "dawn" to be 90 minutes before sunrise, real dawn not occurring.
Rebecca Lindsay, of the National Oceanic and Atmospheric Association (NOAA), said: "This shift disrupts the atmospheric circulation patterns that connect the tropics with the middle latitudes, which in turn modifies the mid-latitude
Zealand Climate Change Research Institute, said low-latitude regions had less variability in day-to-day temperatures when compared with mid-latitude
CHICAGO (CyHAN)- As a result of the geomagnetic storm, magnificent auroras were sighted in several mid-latitude
locations, including Virginia in the United States and in the United Kingdom.
Countries with high and low latitudes are getting wetter but mid-latitude
countries in particular, are drying out.
Since the mid-latitude
storm is critical to the global general circulation that transports heat and moisture from low latitudes to the polar regions, we can expect that the storms modulated by Asian pollution will affect the weather in the Northern Hemisphere.
"Summer is used in mid-latitude
countries that have four seasons, like the US," forecaster Glaiza Escullar said.
