The westerlies, anti-trades, [2] or prevailing westerlies, are prevailing winds from the west toward the east in the middle latitudes between 30 and 60 degrees latitude. They originate from the high-pressure areas in the horse latitudes (about 30 degrees) and trend towards the poles and steer extratropical cyclones in this general manner. [ 3 ]
A western disturbance is an extratropical storm originating in the Mediterranean region that brings sudden winter rain to the northwestern parts of the Indian subcontinent, [1] [2] which extends as east as up to northern parts of Bangladesh and South eastern Nepal. [3] It is a non-monsoonal precipitation pattern driven by the westerlies.
A westerly wind burst is defined by Harrison and Vecchi (1997) as sustained winds of 25 km/h (16 mph) over a period of 5–20 days. [3] However, no concrete definition has been determined, with Tziperman and Yu (2007) defining them as having winds of 14 km/h (8.7 mph) and lasting "at least a few days".
The westerlies play an important role in carrying the warm, equatorial waters and winds to the western coasts of continents, [13] [14] especially in the southern hemisphere because of its vast oceanic expanse. The westerlies explain why coastal Western North America tends to be wet, especially from Northern Washington to Alaska, during the winter.
Buran (a wind which blows across eastern Asia. It is also known as Purga when over the tundra); Karakaze (strong cold mountain wind from Gunma Prefecture in Japan); East Asian Monsoon, known in China and Taiwan as meiyu (梅雨), in Korea as jangma (), and in Japan as tsuyu (梅雨) when advancing northwards in the spring and shurin (秋霖) when retreating southwards in autumn.
Now I have grown into 30 to 45 minutes of walking five days a week for at least two miles. These three changes made the biggest difference in my weight-loss results. I made healthy swaps with WW.
According to recent observations, early signs of spring have already begun in the southern United States. In the Southeast, the spring leaf-out process is 1-2 weeks later than the long-term average.
Crombie often saw the birds form patterns and abstract shapes, their varying densities appearing like the subtle gradations of paint strokes. The photographer became convinced that, with enough ...
