Italian Climate

Climate and weather are two completely different things. Climate is what it's supposed to be like outside, and weather is what you actually get. Weather happens atmosphere, but not just anywhere in the atmosphere. The atmosphere is approximately 32,000 km or 20,000 miles thick. The way I see it is that the crust of the earth is it's skin, and the atmosphere is can be considered either the hairs on the skin that protect from heat and cold, or a mystic aura that protects the body from incoming UV rays and holds us together.
The layers of the atmosphere
Troposphere- Where the weather happens
Tropopause- The top of the Troposphere
Stratosphere- A stable area where the temperature increases;
Ozone found here
Mesosphere- The middle
Thermosphere/ Exosphere- the otter layers of the atmosphere
It starts with Water Vapor, which is variable from place to place. The ability to hold moisture is a function of temperature.How much water is in the air in a certain area effects how the weather is. The atmosphere is divided into section, each doing their own part to help protect the Earth from solar particles and UV radiation.

The way temperature works from radiation balance. Insolation (The amount of solar radiation received at a certain area). The radiation from sun is projected to Earth, and while some is absorbed to heat the planet, the rest is reflected. The radiation that is absorbed gets turned into thermal energy which increases the temperature of the area. The reflected energy is reflected because of an objects albedo (the colour or hue of an item determines how much energy is collected from heat. White reflects heat and black collects it).

Earth's Atmosphere Pressure. Each section represents how the weather in that area functions. H stands for High pressure which comes with good weather and clear skies. L stands for low pressure and normally means cool weather and/or storms.
The Earth circulates like the human body. The latitudinal lines across the planet can be categorized based off the type of pressure that occurs.


Koppen ClassificationChart
Another way of categorizing the weather is the Koppen climate classification chart. This chart categorizes the different regions of the world into sections that can relate to one another. According to the chart, places that lie in the same relative latitudes SHOULD have similar weather. This is both true and false. As you can see from the chart, Northern Africa is all categorized similarly, as is Russia and Canada. However when looking at the U.S. and Italy, there are spots that match such as the coastlines, and parts that don't such as the middle around Colorado. Italy is considered to have several different categorizations on Koppen's chart.
Rome in the summer. Standard Csa Climate.
Low vegetation and hot temperatures.

The first is a Csa. Csa shows that this section of Italy has a warm temperature, with dry and hot summers. Sections of Italy that fall under this category are like Rome and Naples. The average temperature is around 74-78 degrees with lots of precipitation in the winter, but rare snowfall. The plants that live there have adapted to the cold winters and low summer precipitation.






Potenza, Italy. Csb Climate
Italy also is considered a Csb, which is verey similar to a Csa, just meaning that the summers are warm instead of hot. These areas have more rain during the winter and experience snowfall. These areas are also higher elevated.

Florence, Italy. Cfa Climate
Getting more towards the mountains and valleys, were agriculture flourishes, cities such as Milan, Florence, and Venice have Cfa climates, indicating they have hot and wet summers, and mild winters. Places like this tend to be northern inland, and Southern Italy. These climates have no dry seasons.

Other places in the mountains have Dfb and Dfc climates which mean they have cold winters with lots of snow and precipitation, and cool-mild summers.
Rhemes- Notre- Dame, Winter. Dfc climate
Rhemes- Notre- Dame, Summer. Dfc climate
