INDEX

  • Introduction

  • Difference between climate and atmospheric weather

  • Climatic elements:

    • Rainfall

    • Clouds

    • Atmospheric pressure

    • Humidity

    • Temperature

    • Wind


Meteorological data collection

Our project consists in the collection of meteorological data according to the instructions given to us by the protocols of GLOBE. These data are needed to determine whether climate changes are occurring globally. We have compared these data with those observed in other countries around the world, participating to the Globe project.

Introduction


Meteorological data collection

Climate is the average weather at a given location, observed for about 20-30 years. Climate is mainly a function of the inclination of the sun’s rays on the Earth's surface, considered as a function of the latitude. It determines flora and fauna and influences the economic activities, the habits and culture of the people inhabiting the territory.

Difference between climate and

atmospheric weather


Meteorological data collection

In meteorology, atmospheric weather is defined as the set of all weather phenomena that occur in the atmosphere at a given point in time. It is different from climate because the latter represents the average state of the atmosphere over a period of about thirty years. What characterizes the weather is called meteorological variability that can overlap the trend of natural climate in the medium - long term.

Rainfall

Rain is the most common type of atmospheric precipitation and it happens when separate drops of water fall from the clouds to the ground. The rain plays a very important role in the water cycle. Water evaporates from the oceans, condenses in the clouds and falls to the ground, then it returns to the ocean through groundwater and rivers, thus repeating the cycle. In this way water becomes available to the biosphere, allowing the development of flora and fauna and becoming available for human beings.


Meteorological data collection

With a pluviometer we collected rain, measured the millimetres fall and reported these data in the protocols.

Meteorological data collection

Clouds

Clouds are made by verylittle water particles, ice crystals or both of them. They are suspended in the athmosphere and they do not usually touch the ground.


Meteorological data collection

Thanks to GLOBE’s guide we can say what type of clouds are in the sky in a specific moment of the day.

Our work


Meteorological data collection

Atmospheric pressure is the pressure exerted by a column of air with the height of the Earth’s atmosphere on a surface of 1 cm2

Atmospheric pressure


Meteorological data collection

Our work!!

We gauged atmospheric pressure with a barometer!


Meteorological data collection

Humidity

Atmosphere is composed by a mixture of gases, one of which is water vapour. Water vapour is added to atmosphere by evaporation and transpiration and it is removed when it condenses or when it freezes and crashes.

Relative humidity (RH) is the ratio between water vapour’s quantity in the atmosphere and the maximum possible one at the same temperature.

Absolute humidity is the water vapour’s quantity in the atmosphere.


Meteorological data collection

To measure the relative humidity we used an hygrometer

Our work


Meteorological data collection

Atmospheric temperature

Temperature is the physical quantity that indicates body or system’s thermal state.


Meteorological data collection

To report temperature we used a digital thermometer

For maximum temperature

For minimum temperature

For actual temperature


Meteorological data collection

Maxim temperature

Actual temperature

Minimum temperature

We report the 3 temperatures then we press the key “clear” every day to reset data just wrote.


Meteorological data collection

Wind

Wind is an horizontal movement of air masses as a result of the vertical movements of atmospheric air masses.


Meteorological data collection

To monitor the direction of the wind we used a little flag and a compass rose

We are watching the clouds...

We are wathing wind direction and then we write data on Globe’s scheemes.
