derecho

(dərā`chō), a long-lived windstorm over a wide expanse that is associated with a line of rapidly moving thunderstorms or showers. The winds in a derecho generally exceed 57 mph (92 kph) and may reach 100 mph (161 kph) or more; derecho winds are produced by clusters of downbursts, with stronger winds being produced by microbursts within downbursts. The line of storms associated with a derecho typically takes on a broadly curved or bowed shape, known as a bow echo from its appearance on radar. A serial derecho, usually associated with a strong, moving low pressure system, contains multiple bow echoes within a squall line that usually is hundreds of miles long and traverses an extensive area. A progressive derecho is typically associated with a weak surface low pressure area and with a line of thunderstorms less than 250 mi (400 km) long; the squall line usually remains relatively narrow as it progresses and may contain only a single bow echo. Hybrid derechos have characteristics of both serial and progressive derechos. Derechos typically cause so-called straight-line wind damage, in which the destruction is aligned in one general direction. Derecho winds can topple trees and power lines, overturn high-profile trucks and other vehicles, and even overturn mobile homes; the sudden, widespread destruction they cause can lead to prolonged power outages.

Este escrito presenta una metodologia Dogmatica, en donde se emplea un metodo filosofico-doctrinal, que recoge los grandes aportes de Hart y varios de los teoricos que trabajan su obra; en donde la intencion es ver un punto diferente a la clasica concepcion del Derecho como sistema Juridico estatico.
Para Hart en el concepto de Derecho, el Derecho internacional constituye una nocion completamente diferente a la clasica nocion de Derecho basada en reglas que conforman el saber puramente hartiano, en la medida en que este derecho adolece de una normatividad clara, expresa en forma de tribunales con jurisdiccion compulsiva, y de un conjunto de sanciones determinada.
