The planetary wind system is primarily influenced by various factors. Let`s analyze each option to understand which one is not connected to the wind system:

Option 1: Latitudinal variation of the atmospheric heating - This factor is indeed connected to the planetary wind system. The differential heating of the Earth`s surface at different latitudes leads to the formation of pressure gradients, which in turn drive the movement of winds.

Option 2: Emergence of the pressure belt - The emergence of pressure belts is closely tied to the planetary wind system. These pressure belts, such as the equatorial low-pressure belt and the subtropical high-pressure belt, are responsible for the circulation of winds on a global scale.

Option 3: Earth`s revolution around the Sun - Alert - The correct answer should be "option-3 Earth`s revolution around the Sun." While the Earth`s revolution around the Sun does have an impact on seasons, it is not directly connected to the planetary wind system. The wind patterns are mainly influenced by the distribution of pressure belts.

Option 4: Migration of the pressure belts due to the apparent path of the Sun - The migration of pressure belts due to the apparent path of the Sun plays a significant role in the planetary wind system. The shifting of the pressure belts during different seasons
