Surface and Characteristics
The Moon is the only celestial body visited by humans, orbiting the Earth at an average distance of 238,855 miles. It is a rocky, airless body with a diameter of 2,159 miles, making it about one-quarter the size of Earth. The Moon’s surface is marked by numerous craters, which are the result of impacts by asteroids and comets over billions of years. These craters range in size from microscopic to hundreds of miles wide, with some of the largest being visible from Earth with the naked eye. Additionally, the Moon has vast, dark plains known as maria, which were formed by ancient volcanic eruptions.
Tidal Effects and Influence on Earth
The Moon’s gravitational pull has a significant impact on Earth, particularly on its tides. The Moon’s gravity creates high and low tides in the oceans, which occur twice a day as the Moon passes overhead. These tides play a crucial role in marine ecosystems and coastal processes. Furthermore, the Moon’s gravity also affects Earth’s rotation, gradually slowing it down by about 1.4 milliseconds per century. This effect has implications for the Earth’s day length and the calibration of clocks and timekeeping systems. Moreover, the Moon’s presence stabilizes Earth’s axis, preventing extreme shifts in its tilt and contributing to the relatively stable climate conditions on our planet.
Seasonal Humidity Patterns
Bellevue, Washington experiences distinct seasonal variations in humidity levels. During the summer months (June to August), the city typically has high humidity, often reaching up to 80% or more. This is due to the moist, warm Pacific air that brings in moisture from the ocean. As the seasons transition to fall (September to November), the humidity levels gradually decrease as temperatures cool and the air becomes drier. Winter (December to February) brings the lowest humidity levels, typically ranging from 45% to 65%. During this time, the air is cold and dry, with less moisture in the atmosphere.
Impact on Human Comfort
Humidity plays a significant role in human comfort. High humidity levels, especially in summertime, can make people feel hot and uncomfortable as it hinders the evaporation of sweat from the body, leading to increased sweating and a sticky sensation on the skin. Additionally, high humidity can exacerbate respiratory issues, such as asthma and allergies, by trapping pollutants and allergens in the air. Conversely, low humidity levels during winter can cause dry skin and irritation of the respiratory tract. Maintaining appropriate humidity levels is crucial for the well-being and comfort of Bellevue residents.
Wind Patterns in Bellevue, United States
Bellevue, situated in the Puget Sound region of Washington, experiences a temperate climate characterized by moderate temperatures and abundant precipitation. The city’s wind patterns are influenced by its proximity to the Pacific Ocean, the Cascade Mountains, and the Puget Sound topography. Prevailing winds in Bellevue typically originate from the west or southwest, bringing moisture from the Pacific Ocean. These winds often reach speeds of 10-15 miles per hour during the day, decreasing slightly at night. During winter months, Bellevue may experience stronger winds associated with Pacific storms, known as Pineapple Expresses. These storms can bring sustained winds of up to 30 miles per hour, gusts of up to 50 miles per hour, and heavy rain or snowfall.
Local Wind Phenomena
In addition to the prevailing westerly winds, Bellevue also experiences localized wind phenomena. These include:
- Katabatic Winds: During cold winter nights, heavier cold air descends from the Cascade Mountains into the Bellevue area. This phenomenon, known as katabatic winds, creates downslope winds that can reach speeds of up to 20 miles per hour.
- Puget Sound Convergence Zone: The Puget Sound Convergence Zone (PSCZ) is a narrow band of thunderstorms that occasionally forms over the Puget Sound region. When the PSCZ passes through Bellevue, it can bring strong winds up to 40 miles per hour, lightning, heavy rain, and hail.
- Chinook Winds: Chinook winds are warm, dry winds that descend from the eastern slopes of the Cascade Mountains. These winds can reach Bellevue on occasion, bringing rapid temperature increases and wind speeds up to 60 miles per hour.
