Hurricane Nora (2003)
Hurricane Nora was the fourth of five tropical cyclones to make landfall (meteorology), landfall in Mexico during the 2003 Pacific hurricane season. The fourteenth tropical cyclone naming, named storm and fifth hurricane of the season, Nora developed on October 1 from a tropical wave. It slowly intensified as it moved northwestward, intensifying into a hurricane on October 4. That day, Nora rapidly intensified to its peak of 100 mph (160 km/h), but the larger Hurricane Olaf (2003), Hurricane Olaf to its east prevented further strengthening. An approaching trough (meteorology), trough turned the rapidly weakening system to the east toward Mexico. By October 7, it was downgraded to a tropical depression. Although it no longer met the criteria for being a tropical cyclone, the National Hurricane Center continued issuing advisories due to the cyclone's proximity with land. Nora unexpectedly redeveloped an area of thunderstorms and moved ashore near Mazatlán, ...

Tropical Cyclogenesis
Tropical cyclogenesis is the development and strengthening of a tropical cyclone in the atmosphere. The mechanisms through which tropical cyclogenesis occurs are distinctly different from those through which temperate cyclogenesis occurs. Tropical cyclogenesis involves the development of a warm-core cyclone, due to significant convection in a favorable atmospheric environment. Tropical cyclogenesis requires six main factors: sufficiently warm sea surface temperatures (at least ), atmospheric instability, high humidity in the lower to middle levels of the troposphere, enough Coriolis force to develop a low-pressure center, a pre-existing low-level focus or disturbance, and low vertical wind shear. Tropical cyclones tend to develop during the summer, but have been noted in nearly every month in most basins. Climate cycles such as ENSO and the Madden–Julian oscillation modulate the timing and frequency of tropical cyclone development. There is a limit on tropical cyclone i ...

Hydrometeorological Prediction Center
The Weather Prediction Center (WPC), located in College Park, Maryland, is one of nine service centers under the umbrella of the National Centers for Environmental Prediction (NCEP), a part of the National Weather Service (NWS), which in turn is part of the National Oceanic and Atmospheric Administration (NOAA) of the U.S. Government. Until March 5, 2013 the Weather Prediction Center was known as the Hydrometeorological Prediction Center (HPC). The Weather Prediction Center serves as a center for quantitative precipitation forecasting, medium range forecasting (three to eight days), and the interpretation of numerical weather prediction computer models. The Weather Prediction Center issues storm summaries on storm systems bringing significant rainfall and snowfall to portions of the United States. They also forecast precipitation amounts for the lower 48 United States for systems expected to impact the country over the next seven days. Advisories are also issued for tropical cyclo ...

Nayarit
Nayarit (), officially the Free and Sovereign State of Nayarit ( es, Estado Libre y Soberano de Nayarit), is one of the 31 states that, along with Mexico City, comprise the Federal Entities of Mexico. It is divided in 20 municipalities and its capital city is Tepic. It is bordered by the states of Sinaloa to the northwest, Durango to the north, Zacatecas to the northeast and Jalisco to the south. To the west, Nayarit has a significant share of coastline on the Pacific Ocean, including the islands of Marías and Marietas. The beaches of San Blas and the so-called "Riviera Nayarit" are popular with tourists. Besides tourism, the economy of the state is based mainly on agriculture and fishing. It is also one of two states where the tarantula species ''Brachypelma klaasi'' is found, the other being Jalisco. Home to Uto-Aztecan indigenous peoples such as the Huichol and Cora, the region was exposed to the ''conquistadores'', Hernán Cortés and Nuño de Guzmán, in the 16t ...

Servicio Meteorológico Nacional (Mexico)
The Servicio Meteorológico Nacional (SMN) is Mexico's national weather organization. It collects data and issues forecasts, advisories, and warnings for the entire country. History A presidential decree founded El Observatorio Meteorológico y Astrónomico de México (The Meteorological and Astronomical Observatory of Mexico) on February 6, 1877 as part of the Geographic Exploring of the National Territory commission. By 1880, it became an independent agency located at Chapultepec Castle, then encompassing six observatories. In 1901, the Servicio Meteorologia Nacional was formed with 31 sections for each state and 18 independent observatories which reported back to the central office in Tacubaya via telegraph. It joined the World Meteorological Organization in 1947. By 1980, the organization included 72 observatories, of which eight launched weather balloons and radiosondes, and five radars serviced the country. In 1989, it became a subagency of the General de Administracion d ...

Tropical Cyclone Warnings And Watches
Tropical cyclone warnings and watches are alerts issued by national weather forecasting bodies to coastal areas threatened by the imminent approach of a tropical cyclone of tropical storm or hurricane intensity. They are notices to the local population and civil authorities to make appropriate preparation for the cyclone, including evacuation of vulnerable areas where necessary. It is important that interests throughout the area of an alert make preparations to protect life and property, and do not disregard it on the strength of the detailed forecast track. Western hemisphere New tropical cyclone position and forecast information is available at least every twelve hours in the Southern Hemisphere and at least every six hours in the Northern Hemisphere from Regional Specialized Meteorological Centers and Tropical Cyclone Warning Centers. In conjunction with the National Hurricane Center, the national meteorological and hydrological services of Central America, the northern Atlan ...

Special Sensor Microwave/Imager
The Special Sensor Microwave/Imager (SSM/I) is a seven-channel, four-frequency, linearly polarized passive microwave radiometer system.Hollinger, J.P. 1989: ''DMSP Special Sensor Microwave/Imager Calibration/Validation''. Final Report, Vol. I., Space Sensing Branch, Naval Research Laboratory, Washington D.C. It is flown on board the United States Air Force Defense Meteorological Satellite Program (DMSP) Block 5D-2 satellites. The instrument measures surface/atmospheric microwave brightness temperatures (TBs) at 19.35, 22.235, 37.0 and 85.5 GHz. The four frequencies are sampled in both horizontal and vertical polarizations, except the 22 GHz which is sampled in the vertical only. The SSM/I has been a very successful instrument, superseding the across-track and Dicke radiometer designs of previous systems. Its combination of constant-angle rotary-scanning and total power radiometer design has become standard for passive microwave imagers, e.g. TRMM Microwave Imager, AMSR. ...

Eye (cyclone)
The eye is a region of mostly calm weather at the center of tropical cyclones. The eye of a storm is a roughly circular area, typically in diameter. It is surrounded by the ''eyewall'', a ring of towering thunderstorms where the most severe weather and highest winds occur. The cyclone's lowest barometric pressure occurs in the eye and can be as much as 15 percent lower than the pressure outside the storm. In strong tropical cyclones, the eye is characterized by light winds and clear skies, surrounded on all sides by a towering, symmetric eyewall. In weaker tropical cyclones, the eye is less well defined and can be covered by the central dense overcast, an area of high, thick clouds that show up brightly on satellite imagery. Weaker or disorganized storms may also feature an eyewall that does not completely encircle the eye or have an eye that features heavy rain. In all storms, however, the eye is the location of the storm's minimum barometric pressure—where the atmospheric pr ...
