Pineapple Express
Pineapple Express is a non-technical term for a meteorological phenomenon characterized by a strong and persistent large-scale flow of warm moist air, and the associated heavy precipitation both in the waters immediately northeast of the Hawaiian Islands and extending northeast to any location along the Pacific coast of North America. A Pineapple Express is an example of an atmospheric river, which is a more general term for such relatively narrow corridors of enhanced water vapor transport at mid-latitudes around the world. Causes and effects A ''Pineapple Express'' is driven by a strong, southern branch of the polar jet stream and is marked by the presence of a surface frontal boundary which is typically either slow or stationary, with waves of low pressure traveling along its length. Each of these low-pressure systems brings enhanced rainfall. The conditions are often created by the Madden–Julian oscillation, an equatorial rainfall pattern which feeds its moisture into t ...

Sierra Nevada (U
The Sierra Nevada () is a mountain range in the Western United States, between the Central Valley (California), Central Valley of California and the Great Basin. The vast majority of the range lies in the state of California, although the Carson Range spur lies primarily in Nevada.

The Sierra runs north-south and its width ranges from to across east–west. Notable features include General Sherman (tree), General Sherman, the largest tree in the world by volume; Lake Tahoe, the largest alpine lake in North America; Mount Whitney at , the highest point in the contiguous United States; and Yosemite Valley sculpted by glaciers from one-hundred-million-year-old granite, containing List of waterfalls in Yosemite National Park, high waterfalls.

San Marcos Pass
San Marcos Pass (Chumash: ''Mistaxiwax'') is a mountain pass in the Santa Ynez Mountains in southern California. It is traversed by State Route 154. The pass crosses the Santa Ynez through a southwestern portion of Los Padres National Forest, and connects Los Olivos (and the Santa Ynez Valley) with Santa Barbara, California along the Pacific coast. The road has been designated as a daylight-headlight highway by the California Highway Patrol and Caltrans because of frequent accidents, particularly around the exit for Lake Cachuma. Geography The pass is one of three passages across the steep Santa Ynez Mountains, and the nearest to Santa Barbara. The Painted Cave community and Laurel Springs Ranch near Chumash Painted Cave SHP is four miles east of San Marcos Pass via East Camino Cielo Road, which intersects with SR 154 right at the summit. San Marcos Pass is a shorter but hillier alternative to using Highway 101 through Gaviota Pass. "Battle" of Fremont's Pass No shots w ...

Flooding
A flood is an overflow of water ( or rarely other fluids) that submerges land that is usually dry. In the sense of "flowing water", the word may also be applied to the inflow of the tide. Floods are an area of study of the discipline hydrology and are of significant concern in agriculture, civil engineering and public health. Human changes to the environment often increase the intensity and frequency of flooding, for example land use changes such as deforestation and removal of wetlands, changes in waterway course or flood controls such as with levees, and larger environmental issues such as climate change and sea level rise. In particular climate change's increased rainfall and extreme weather events increases the severity of other causes for flooding, resulting in more intense floods and increased flood risk. Flooding may occur as an overflow of water from water bodies, such as a river, lake, or ocean, in which the water overtops or breaks levees, resulting in some of t ...

1997–98 El Niño Event
The 1997–1998 El Niño was regarded as one of the most powerful El Niño–Southern Oscillation events in recorded history, resulting in widespread droughts, flooding and other natural disasters across the globe. It caused an estimated 16% of the world's reef systems to die, and temporarily warmed air temperature by compared to the usual increase of associated with El Niño events. It led to a severe outbreak of Rift Valley fever after extreme rainfall in north-eastern Kenya and southern Somalia. It also led to record rainfalls in California during the water season of 1997–98 and one of Indonesia's worst droughts on record. 1998 ultimately became the warmest year in recorded history (up until then). Meteorological progression In January 1997, probes gathering information on deep water temperatures discovered an area of unusually warm water, centered around 150 meters depth, across the western half of the Pacific Ocean. About below the surface, water temperatures were ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
