Lee-side Frontogenesis in the Rocky Mountains
The development and motion of fronts associated with lee-side troughs on large mountain barriers has been investigated. These fronts differ from ordinary cold fronts in their horizontal temperature field, which is characterized by a sinusoidal thermal ridge. The thermal ridge intensifies, while remaining stationary with respect to the mountains, and moves eastward upon the approach of a Pacific...
متن کاملGas Resources and Production in the Rocky Mountains
Natural gas demand in the United States has been increasing for the last 15 years and is expected to increase substantially in the next 20 years (Energy Information Administration, 2003; National Petroleum Council, 1999). Demand is projected to increase in all sectors, especially electricity generation (Figure 1.1). In fact, 80 percent of projected electricity generation capacity additions thro...
متن کاملWood dynamics in headwater streams of the Colorado Rocky Mountains
[1] An 11-year monitoring study begun in 1996 evaluates wood mobility in five Colorado Rocky Mountain streams. Each channel reach is 40–70 m in length. Initial surveys included channel dimensions and arrangement of each piece of wood. Annual resurveys focused on wood arrangement and persistence. Average diameter of 15 cm and length of 3.2 m varied little among sites. Average yearly mobility ran...
متن کاملRegionalization of fire regimes in the Central Rocky Mountains, USA
a r t i c l e i n f o Fire is one of the most important natural disturbances in the coniferous forests of the US Rocky Mountains. The Rocky Mountains are separated by a climatic boundary between 40° and 45° N, which we refer to as the central Rocky Mountains (CRM). To determine whether the fire regime from the CRM was more similar to the northern Rocky Mountains (NRM) or southern Rocky Mountain...
