It is necessary to understand the net effect clouds have on the climate because adaptations to climate change will be made and adjusted based on such. Some clouds like stratiform clouds have an overall cooling effect on the climate while other clouds like cirrus clouds have an overall warming effect on the climate, so the net effect clouds have on the climate is currently unknown. Stratiform clouds reflect sunlight and therefore are important to combat climate change. It is important to look into the movement of stratiform clouds because it affects downstream weather like precipitation, humidity, and our daily lives. One aspect that affects cloud movement is wind speeds, and due to an increased number of aerosols in the atmosphere, there has been a decrease in wind speeds. We want to determine if the number of aerosols in the atmosphere has a direct effect on the movement of stratiform clouds in Europe. We will use the International Cloud Climatology project to get data on the characteristics of clouds (movement, and type of clouds), use the ERA5 data set for wind speed data, and use the NASA MODIS observations for aerosol data. The data will then be merged, so statistical analysis can be performed. A regression/correlation analysis will be performed three times to determine the relationship between wind speed and the number of aerosols in the atmosphere, wind speed and cloud movement, and cloud movement and number of aerosols in the atmosphere. This data will help us better understand cloud movement, downstream weather patterns, and how to improve our adaptations to climate change.
