What is dbz

Despite the TV series officially ending in Japan in , and in in North America, Dragon Ball Z video games are created nearly every year for almost every console on the market, helping to introduce the Dragon Ball Z series to younger generations that never got a chance to see it air on television.

These games usually do very well in the market. Popular sites such as YouTube have attracted large Dragon Ball Z fan communities throughout the last few years, and Dragon Ball related videos receive many views. All of these examples showcase the incredible popularity of Dragon Ball Z in many countries of the world. The original author of the manga, Akira Toriyama , held a great deal of respect for both the Dragon Ball and Dragon Ball Z anime and those that developed them.

Toriyama also admired the fact that the anime managed to possess original stories created by the animation team and stated that he considered the Dragon Ball anime to be equal in importance to the Dragon Ball manga.

The movies were released on both VHS and Laserdisc format. The video and audio transfers of the show used on these DVDs came off of the Fuji TV master tapes of the show, as this allowed Toei to put out a far superior and completely accurate version of the show on DVD, which was helpful since the entire plot of a season could be summed up in about ten minutes.

This allowed all episodes to have their original openings, endings, eyecatches, next episode previews, etc. While the packaging and DVD menus are different from the release, and so far no plans have been announced for the two TV specials and the Playdia footage released with the versions, the Audio and Visual quality is the same as those discs found in the Dragon Box release. This release contained all 17 Dragon Ball and Dragon Ball Z theatrical features, containing 8 DVDs in total, along with a book, and two scouters in the form of walkie-talkies.

The video and audio are remastered; however, the video is cropped to widescreen and contains less picture than the full-screen versions. All Dragon Box releases contain Japanese language audio only with exceptions to foreign-language bonus clips , and no subtitles. These DVDs retained the original Ocean cast for the English track, as well as being one of the first uncut and bilingual releases in the U.

The English versions of these films were also subject to a different treatment than the series; rather than replacing the original music, the original OP and ED themes, as well as background music, were retained. The only noticeable differences besides languages are the inclusion of a few different sound effects which are not present on the original Japanese version.

These films were released as a three-disc boxset by Pioneer. As of August the 31st, , Pioneer's license for video distribution of the first 53 episodes ended, allowing Funimation to re-release them.

At the moment, the rights for these episodes and the first three Dragon Ball Z movies belong to Funimation. As of , Funimation had released uncut versions of their Texas-based English dub on to DVD, with Japanese language track, and English-translation subtitles.

This release does not include the first two sagas, as the rights for the distribution of that episodes were still held by Pioneer Entertainment. Boxsets were release for the Garlic Jr. However, to maximize profits, the DVDs were released out of continuity certain amounts of one section of the series were released, and then Funimation would go back and release others.

With no noticeable numbering visible, this caused frustration to those trying to follow the series from start to finish. Funimation also released Dragon Ball Z movies , finishing the release of the movies with Wrath of the Dragon , the 13th movie. These are all bilingual and subtitled, but do not follow the trend set by Ocean 's first three movies.

Music has been changed and altered, including the insertion of songs from rock bands such as Deftones, Disturbed, Breaking Point, and American Pearl. The movies utilize Funimation's TV series Texas cast , though they also include the original Japanese version with subtitling by Steve Simmons. After acquiring the video rights to the first 53 67 uncut episodes from Pioneer in , Funimation announced that they would release these episodes uncut, with a new 5. The "Ultimate Uncut Special Edition" line was born.

The release would be 22 volumes, bilingual, and extras. Funimation had also acquired the rights for the first three movies from Pioneer in and re-released them. Even though the three had the same cover style, only the first movie was released under the Ultimate Uncut line. All of these movies had a 5.

However, they do not retain the original dub and contain a new English dub produced by Funimation's Texas cast. This version contains different music than the original dub and the Japanese version. Main article: Funimation Remastered Box Sets. All DBZ episodes were to be digitally remastered and released in boxset form. The first season set the entire Vegeta Saga was re-released on February 6, Funimation released a trailer for the new set on the Dragon Ball Z official website.

Funimation released the second season set, containing both the Namek and Captain Ginyu sagas, on May 22, Beginning with this release, several of the in-house voice actors re-dubbed their characters' lines to keep consistency with the remainder of the dub.

The third season set, containing the Frieza Saga , was released on September 18, The fourth season, containing both the Garlic Jr. Season five, containing both the Imperfect and Perfect Cell sagas, was released on May 27, Season six, containing the Cell Games Saga , was released on September 16, Season seven, containing both the Great Saiyaman and World Tournament sagas, was released on November 11, Season eight, containing both the Babidi and Majin Buu sagas, was released on February 10, Season nine, containing both the Fusion and Kid Buu sagas, was released on May 19, The series has been re-transferred at p resolution with digital restoration technology removing all grain and scratches from Funimation's original prints of the series.

It is important to note, however, that like many late 80's-early 90's Toei productions for example, Saint Seiya , Sailor Moon , Marmalade Boy , Ghost Sweeper Mikami, and Slam Dunk , the series was produced on millimeter film which tends to be fairly grainy and soft.

The new restoration was supervised by colorist Steve Franko. The series is presented in a widescreen format 1. Comparison images from the new set show that while there is missing footage on the top and bottom, there is at least additional footage on the right and left that has not appeared in any prior release, having been taken straight from the original Japanese film master recording.

This format change was highly controversial among fans, as this is not how the T. Many fans launched a letter-writing campaign against the release. In response to the negative fan outcry regarding the release's apparent cropping of the source video, a Funimation representative has released a document from the team remastering the video, which explains the logistics of the new release.

This document details how certain areas of the original film are damaged, and admits that though the video is cropped, this release eliminates the grain that was present on prior releases.

It has also been theorized that it is ultimately more inexpensive to transfer the series in and thereby remove the damaged portions of the frame than to repair episodes' worth of damaged film. In this mode, the radar is in its most sensitive operation.

This mode has the slowest antenna rotation rate which permits the radar to sample a given volume of the atmosphere longer. This increased sampling increases the radar's sensitivity and ability to detect smaller objects in the atmosphere than in precipitation mode. A lot of what you will see in clear air mode will be airborne dust and particulate matter. Also, snow does not reflect energy sent from the radar very well. Therefore, clear air mode will occasionally be used for the detection of light snow.

In clear air mode, the radar products update every 10 minutes. When rain is occurring, the radar does not need to be as sensitive as in clear air mode as rain provides plenty of returning signals. In Precipitation Mode, the radar products update every 6 minutes. The colors on the legend are the different echo intensities reflectivity measured in dBZ.

Reflectivity covers a wide range of signals from very weak to very strong. So, a more convenient number for calculations and comparison, a decibel or logarithmic scale dBZ , is used. The dBZ values increase as the strength of the signal returned to the radar increases. Each reflectivity image you see includes one of two color scales. The other scale represents dBZ values when the radar is in precipitation mode dBZ values from 5 to The scale of dBZ values is also related to the intensity of rainfall.

Typically, light rain is occurring when the dBZ value reaches The higher the dBZ, the stronger the rainrate. Depending on the type of weather occurring and the area of the U.

These values are estimates of the rainfall per hour, updated each volume scan, with rainfall accumulated over time. Hail is a good reflector of energy and will return very high dBZ values. Since hail can cause the rainfall estimates to be higher than what is actually occurring, steps are taken to prevent these high dBZ values from being converted to rainfall.

Echoes from objects like buildings and hills appear in almost all radar reflectivity images. This "ground clutter" generally appears within a radius of 25 miles of the radar as a roughly circular region with a random pattern. An mathematical algorithm can be applied to the radar data to remove echoes where the echo intensity changes rapidly in an unrealistic fashion.

These "No Clutter" images are available on the web site. Use these images with caution; ground clutter removal techniques can remove some real echoes, too. Under highly stable atmospheric conditions typically on calm, clear nights , the radar beam can be refracted almost directly into the ground at some distance from the radar, resulting in an area of intense-looking echoes.

This "anomalous propagation " phenomenon commonly known as AP is much less common than ground clutter. Certain sites situated at low elevations on coastlines regularly detect "sea return", a phenomenon similar to ground clutter except that the echoes come from ocean waves.

Radar returns from birds, insects, and aircraft are also rather common. Echoes from migrating birds regularly appear during nighttime hours between late February and late May, and again from August through early November. Return from insects is sometimes apparent during July and August. However, during the peaks of the bird migration seasons, in April and early September, extensive areas of the south-central U. Finally, aircraft often appear as "point targets" far from the radar.

This is a display of echo intensity reflectivity measured in dBZ. The base reflectivity images in Precipitation Mode are available at four radar "tilt" angles, 0. A tilt angle of 0. Viewing multiple tilt angles can help one detect precipitation, evaluate storm structure, locate atmospheric boundaries, and determine hail potential.

The maximum range of the "short range" base reflectivity product is nautical miles about miles from the radar location. This view will not display echoes that are more distant than nm, even though precipitation may be occurring at greater distances. This display is of maximum echo intensity reflectivity measured in dBZ from all four radar "tilt" angles, 0.

This product is used to reveal the highest reflectivity in all echoes. When compared with Base Reflectivity, the Composite Reflectivity can reveal important storm structure features and intensity trends of storms. The maximum range of the "short range" composite reflectivity product is nm about miles from the radar location. This is the velocity of the precipitation either toward or away from the radar in a radial direction.

No information about the strength of the precipitation is given. This product is available for just two radar "tilt" angles, 0. Precipitation moving toward the radar has negative velocity blues and greens. Precipitation moving away from the radar has positive velocity yellows and oranges. Precipitation moving perpendicular to the radar beam in a circle around the radar will have a radial velocity of zero, and will be colored grey. Where the display is colored pink coded as "RF" on the color legend on the left side , the radar detected an echo but was unable to determine the wind velocity, due to inherent limitations in the Doppler radar technology.

RF stands for "Range Folding". The true wind direction can be determined on a radial velocity plot only where the radial velocity is zero grey colors. Where you see a grey area, draw an arrow from negative velocities greens and blues to positive velocities yellows and oranges so that the arrow is perpendicular to the radar beam.

The radar beam can be envisioned as a line connecting the grey point with the center of the radar. To think of it another way, draw the wind direction line so that the wind will be blowing in a circle around the radar no radial velocity, only tangential velocity. In order to determine the wind direction everywhere on the plot, a second Doppler radar positioned in a different location would be required.

Research programs frequently use such "dual Doppler" techniques to generate a full 3-D picture of the winds over a large area. If you see a small area of strong positive velocities yellows and oranges right next to a small area of strong negative velocities greens and blues , this may be the signature of a mesocyclone--a rotating thunderstorm.

If the thunderstorm is moving rapidly toward or away from you, the mesocyclone may be harder to detect. In these cases, it is better to subtract off the mean velocity of the storm center, and look at the Storm Relative Mean Radial Velocity. VIL is the amount of liquid water that the radar detects in a vertical column of the atmosphere for an area of precipitation. High values are associated with heavy rain or hail.

VIL values are computed for each 2. Evidence of very strong updrafts leading to the possibility of severe weather can be seen when comparing the two images. At 1, the fuchsia colored region, visible on the composite image, is all but missing on the base reflectivity.

Remember the old adage "What goes up, must come down", using the color scale, this area is at 65 dBZ on the composite image. It is an area of concern as this is probably hail that has yet to fall. Some or most of the hail may melt before reaching the ground but at the very least, intense, blinding rain may be about to occur near this location. The notches, at 2 and 3, show more rain supported by strong updrafts.

Those locations require additional interrogation to determine what is taking place at these locations which will come from the velocity products. These are hourly rainfall rates only and are not the actual amounts of rain a location receives. The total amount of rain received varies with intensity changes in a storm as well as the storm's motion over the ground.
