1. Sun's Position: In the northern hemisphere, the sun rises in the east and sets in the west. As the Earth rotates, the sun moves across the sky from east to west, reaching the highest point in the southern part of the sky around noon. This means that the southern side of the house receives direct sunlight for a longer duration than the northern side, resulting in higher temperatures.
2. Shadow effect: The northern side of the house often lies in the shadow of the house itself, blocking direct sunlight. As a result, the northern side receives less heat from the sun compared to the southern side.
3. Wind direction: In many regions of the northern hemisphere, the prevailing winds come from the west. These winds tend to be colder, and as they hit the northern side of the house, they can further reduce the temperature.
4. Insulation and Building Materials: The choice of insulation and building materials can also impact temperature differences between the two sides of the house. If there is better insulation on the southern side, it can retain more heat, further contributing to the temperature differences.
However, it's worth noting that specific geographical locations and local weather patterns can influence the exact temperature distribution around the house. For instance, in the southern hemisphere, the south side of the house receives direct sunlight, making it warmer than the northern side.
Therefore, while the general rule applies in the northern hemisphere, it's always essential to consider the specific location and weather conditions when assessing temperature differences in a house.
