Automated Tropical Cyclone Forecasting System
The Automated Tropical Cyclone Forecasting System (ATCF) is a piece of software originally developed to run on a personal computer for the Joint Typhoon Warning Center (JTWC) in 1988, and the National Hurricane Center (NHC) in 1990. ATCF remains the main piece of forecasting software used for the United States Government, including the JTWC, NHC, and Central Pacific Hurricane Center. Other tropical cyclone centers in Australia and Canada developed similar software in the 1990s. The data files with ATCF lie within three decks, known as the a-, b-, and f-decks. The a-decks include forecast information, the b-decks contain a history of center fixes at synoptic hours, and the f-decks include the various fixes made by various analysis center at various times. In the years since its introduction, it has been adapted to Unix and Linux platforms. Reason for development 350 px, ATCF image of Nabi's (2005) previous track, forecast track, along with tropical storm, storm, and hurricane-forc ...

Computer Multitasking
In computing, multitasking is the concurrent computing, concurrent execution of multiple tasks (also known as Process (computing), processes) over a certain period of time. New tasks can interrupt already started ones before they finish, instead of waiting for them to end. As a result, a computer executes segments of multiple tasks in an interleaved manner, while the tasks share common processing resources such as central processing units (CPUs) and main memory. Multitasking automatically interrupts the running program, saving its state (partial results, memory contents and computer register contents) and loading the saved state of another program and transferring control to it. This "context switch" may be initiated at fixed time intervals (pre-emptive multitasking), or the running program may be coded to signal to the supervisory software when it can be interrupted (cooperative multitasking). Multitasking does not require Parallel computing, parallel execution of multiple task ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |

1988 In Computing
1988 was a crucial year in the early history of the Internet—it was the year of the first well-known computer virus, the Morris worm, 1988 Internet worm. The first permanent intercontinental Internet link was made between the United States (National Science Foundation Network) and Europe (Nordunet) as well as the first Internet-based chat protocol, Internet Relay Chat. The concept of the World Wide Web was first discussed at CERN in 1988. The Soviet Union began its major deconstructing towards a mixed economy at the beginning of 1988 and began its Dissolution of the Soviet Union, gradual dissolution. The Iron Curtain began to disintegrate in 1988 as People's Republic of Hungary, Hungary began allowing freer travel to the Western world. The first extrasolar planet, Gamma Cephei Ab (confirmed in 2003), was detected this year and the World Health Organization began its mission to Eradication of polio, eradicate polio.

Workstation
A workstation is a special computer designed for technical or computational science, scientific applications. Intended primarily to be used by a single user, they are commonly connected to a local area network and run multi-user operating systems. The term ''workstation'' has been used loosely to refer to everything from a mainframe computer terminal to a Personal computer, PC connected to a Computer network, network, but the most common form refers to the class of hardware offered by several current and defunct companies such as Sun Microsystems, Silicon Graphics, Apollo Computer, Digital Equipment Corporation, DEC, HP Inc., HP, NeXT, and IBM which powered the 3D computer graphics revolution of the late 1990s. Workstations formerly offered higher performance than mainstream personal computers, especially in Central processing unit, CPU, Graphics processing unit, graphics, memory, and multitasking.

Canadian Hurricane Centre
The Canadian Hurricane Centre (CHC; ) is an organisation that monitors and warns of the threat of tropical cyclones such as hurricanes and tropical storms. CHC is a division of the Meteorological Service of Canada (MSC), which is in turn a branch of Environment and Climate Change Canada. Founded in 1987, CHC provides guidance to MSC's weather centres in eastern and Atlantic Canada, and is based in Dartmouth, Nova Scotia. CHC frequently consults with its United States counterpart, the National Hurricane Center in Miami, to coordinate the tracks and positions of storms that pose a threat to Canada. History 1985's Hurricane Gloria and its less-than-expected damage prompted Environment Canada to create the CHC due to confusion between information received from the US National Hurricane Centre and US media and on-the-ground information and observations. Its first hurricane warnings were issued in 2008 for Hurricane Kyle, which struck near Yarmouth, Nova Scotia on September 28, 2008, ...

Dvorak Technique
The Dvorak technique (developed between 1969 and 1984 by Vernon Dvorak) is a widely used system to estimate tropical cyclone intensity (which includes tropical depression, tropical storm, and hurricane/typhoon/intense tropical cyclone intensities) based solely on visible and infrared Weather satellite, satellite images. Within the Dvorak satellite strength estimate for tropical cyclones, there are several Pattern recognition, visual patterns that a cyclone may take on which define the upper and lower bounds on its intensity. The primary patterns used are curved rainband, band pattern (T1.0-T4.5), Wind shear#Effects on tropical cyclones, shear pattern (T1.5–T3.5), central dense overcast (CDO) pattern (T2.5–T5.0), central cold cover (CCC) pattern, banding eye pattern (T4.0–T4.5), and Eye (cyclone), eye pattern (T4.5–T8.0). Both the central dense overcast and embedded eye pattern use the size of the CDO. The CDO pattern intensities start at T2.5, equivalent to minimal trop ...
