Moon Phases in Drammen, Norway

The moon’s appearance and position in the sky undergo constant changes throughout the month, known as moon phases.

In Drammen, Norway, the moon phases follow the same general pattern as they do in other parts of the world.

The moon goes through four main phases: new moon, first quarter, full moon, and third quarter. During a new moon, the moon is located between the Earth and the sun, making the side of the moon facing Earth completely dark. The first quarter occurs when the moon has moved 90 degrees around the Earth, creating a half-illuminated crescent on the moon’s Earth-facing side. The full moon occurs when the moon is opposite the sun, leading to full illumination of the side of the moon facing Earth. Lastly, the third quarter happens when the moon moves another 90 degrees, showing a half-illuminated crescent on the opposite side of the moon from the first quarter.

Relative Humidity in Drammen, Norway

Relative humidity in Drammen, Norway, varies throughout the year, influenced by seasonal changes and proximity to the Oslofjord. During the colder months, from November to March, relative humidity levels are generally higher, often reaching 80-90% due to increased condensation and less evaporation. In contrast, the summer months, from June to August, experience lower relative humidity levels, typically ranging from 55-70%. This is attributed to higher temperatures, reduced precipitation, and increased evaporation.

Seasonal Variations

Spring and autumn in Drammen exhibit transitional humidity patterns. In April and May, relative humidity gradually decreases as temperatures rise and evaporation increases. However, in September and October, humidity levels tend to rise again as temperatures decline and condensation becomes more prevalent. Additionally, the proximity to the Oslofjord can significantly impact local humidity conditions, particularly during windy periods when moisture from the fjord is carried inland.

Potential and Challenges

Drammen, Norway, has a relatively low solar potential compared to southern European countries due to its high latitude and overcast weather conditions. However, there are still opportunities for solar energy development in the region. The city receives an average of 800-900 kilowatt-hours (kWh) of solar radiation per square meter annually, which is comparable to other cities in northern Europe. However, the distribution of solar irradiance is uneven, with winter months receiving significantly less sunlight than summer months.

The main challenge to solar energy development in Drammen is the lack of open land and building surfaces suitable for large-scale solar arrays. Most existing solar installations are small-scale systems on rooftops or residential properties. The city has limited available land for ground-mounted solar farms, and competition for land use from other sectors, such as housing and industry, is high.

Current Development and Future Prospects

Despite the challenges, there is a growing interest in solar energy in Drammen. The city has set a goal of becoming climate neutral by 2030, and solar energy is seen as an important part of achieving this target. Several small-scale solar projects have been implemented, including a solar array on the roof of the Drammensbadet swimming pool and a series of solar panels on public buildings.

The future prospects for solar energy in Drammen are promising. The city is exploring innovative ways to increase solar energy production, such as installing solar panels on the new Drammen Bus Terminal and developing floating solar arrays on the local rivers. As technology improves and costs continue to decline, solar energy is expected to play an increasingly significant role in the city’s energy mix.
