My understanding is that low pressure areas are susceptible to rain. However, high pressure areas have no rain. Now, I want to correlate this with the following areas -
Lower Hutt, Wellington , NZ - It is always windy in this region. Does it mean that Lower Hutt, Wellington has a lower pressure area and that's why it is windy? Is pressure related to the temperature here? If I go by Charles' equation - $pv = ct$, I think that the earth's position with respect to the sun causes variation in temperature and thus the pressure varies. Is my understanding correct?
Madhya pradesh, India - In the central part of Madhya Pradesh, India - it is extremely hot or extremely cold. Also, it rains heavily. Does it mean that the position of the earth with respect to the sun varies widely in each season? Thus, we see extreme of it in each season? Like during summer season - it builds very high pressure. However, during winter the sun shine is almost absent. Thus, it causes low pressures and finally we get rains. But, in order to get rain - we should have a high pressure nearby, right? Otherwise, how wind will flow from high pressure to low pressure? Also, sometimes rains are absent. Why does it happen? Does it mean that the high pressure wasn't high enough?
Bangalore, India - This is quite above the sea level and the weather is generally cloudy. It doesn't become too hot ever. Does it mean that if the area is quite above the sea level it will have a low pressure? But, there is a contrast here - like Wellington - is at a low sea level but it has the low pressure and that's why it is windy.
What concept am I missing here? Please correct my thoughts or or simplify this to me.
