My question is

Why is Milan cooler than Palermo although Milan is in the North and Palermo is in the south of Italy

Does rain fall got to do with it cause Milan has the most rain fall

To understand why Milan is cooler than Palermo, we can look at the climate data for both cities.

First, let's compare the average temperatures in Milan and Palermo. In Milan, the average annual temperature is around 13.5 degrees Celsius (56 degrees Fahrenheit), while in Palermo, the average annual temperature is around 19 degrees Celsius (66 degrees Fahrenheit). This indicates that Palermo generally experiences higher temperatures throughout the year compared to Milan.

Now, let's consider the factors that contribute to these temperature differences. One significant factor is the geographical location. Milan is located in the northern part of Italy, where it is closer to the Alps and continental Europe. The Alps act as a barrier, preventing warm air masses from the south to reach Milan easily. This results in cooler temperatures in Milan.

On the other hand, Palermo is located in the southern part of Italy, closer to the Mediterranean Sea. The sea acts as a heat reservoir, absorbing and releasing heat. Palermo benefits from the warm air masses coming from the south and the Mediterranean Sea, leading to higher temperatures.

Additionally, another factor that can influence the temperature difference between the two cities is rainfall. According to the climate data you provided, Milan does receive more rainfall compared to Palermo. However, it is essential to note that rainfall alone doesn't determine the temperature. While rain can temporarily cool down the air, it does not have a significant long-term impact on the overall temperature difference between Milan and Palermo.

To summarize, the main factors contributing to Milan being cooler than Palermo despite their north-south geographical locations are the proximity to the Alps, which blocks warm air masses, and the influence of the Mediterranean Sea, which brings warmer temperatures to Palermo. The difference in average annual temperatures between the two cities is primarily a result of these geographical and climatic characteristics.
