The winds are that creatures who in spite of being invisible, are always around us sometimes during hot humid summer they are friendly to us while sometimes during winter they are breezing and chilling us, what have you ever thought that who is creating it or else say how does the formation of winds take place, as per categorization there are generally three types of winds:-
- Primary or Planetary winds.
- Secondary or Periodic winds.
- Local winds.
We know that the earth spins around its axis, by the virtue of the spinning motion of earth causes the formation of winds and as such kinds of winds are generated due to the planetary motions they are called primary or planetary winds, in other cases, the winds are also formed due to various seasonal changes like summer, winter and monsoon which are periodic in nature, hence they are called secondary or periodic winds, now you might have intuitively thought about the local winds as the winds which are caused by some local source, but wait a minute what can we tell as local, say the term local means 'belonging to a particular area or belonging in the neighbourhood. is it true? Yes, the winds that are generated at a particular area or region and winds which are limited on the region of its existence are ideally called local winds.
Can you make wind at home?
Let us understand first that as due to different pressure of air at day and night causes a density or pressure difference, which causes the wind formation, so technically speaking wind is a nickname of pressure difference in the air, so now let us rephrase the question that can we make a pressure difference in the air at home, the answer is simply Yes, grab the tip of a blown balloon release it,
Bravo! You have created a wind at home. (But remember the wind you created is not the primary or secondary wind, let's leave that task to the almighty)
