animated, seamless repeatable background patterns for typhoon

A typhoon is a mature tropical cyclone that develops between 180° and 100°E in the Northern Hemisphere. This region is referred to as the Northwestern Pacific Basin, and is the most active tropical cyclone basin on Earth, accounting for almost one-third of the world's annual tropical cyclones. For organizational purposes, the northern Pacific Ocean is divided into three regions: the eastern (North America to 140°W), central (140°W to 180°), and western (180° to 100°E). The Regional Specialized Meteorological Center (RSMC) for tropical cyclone forecasts is in Japan, with other tropical cyclone warning centers for the northwest Pacific in Hawaii (the Joint Typhoon Warning Center), the Philippines and Hong Kong. While the RSMC names each system, the main name list itself is coordinated among 18 countries that have territories threatened by typhoons each year.Within the northwestern Pacific, there are no official typhoon seasons as tropical cyclones form throughout the year. Like any tropical cyclone, there are a few main requirements for typhoon formation and development: (1) sufficiently warm sea surface temperatures, (2) atmospheric instability, (3) high humidity in the lower to middle levels of the troposphere, (4) enough Coriolis effect to develop a low pressure center, (5) a pre-existing low level focus or disturbance, and (6) a low vertical wind shear. While the majority of storms form between June and November, a few storms do occur between December and May (although tropical cyclone formation is at a minimum during that time). On average, the northwestern Pacific features the most numerous and intense tropical cyclones globally. Like other basins, they are steered by the subtropical ridge towards the west or northwest, with some systems recurving near and east of Japan. The Philippines receive the brunt of the landfalls, with China and Japan being impacted slightly less. Some of the deadliest typhoons in history have struck China. Southern China has the longest record of typhoon impacts for the region, with a thousand-year sample via documents within their archives. Taiwan has received the wettest known typhoon on record for the northwest Pacific tropical cyclone basins.

Usage

Animated repeating patterns can be used in various ways, such as in website background, or to fill HTML / SVG elements. You can also use them as slide / video background.

Here is an example of using animated pattern as background of an icon animation:

<div
  style="background:url(/your-pattern-url)">
  <img src="your-icon-url">
</div>

Formats

All patterns can be generated in SVG / APNG / GIF formats. PNG sequence or static PNG are also available. To choose the right format for yourself, you should check the compatibility and quality of these file format before using them.

GIF

Provides the best compatibility, while big in size and low in quality. supports only up to 256 colors at most.

Supported by all browsers, even by old browser such as IE5 or Netscape.

SVG

Gives the best quality and file size but is CPU-intensive to render. Animation is more likely to lag when browser is busy

Animated SVG is not supported by IE or Edge.

APNG

Provides similar quality to SVG and is supported by most modern browsers, including Microsoft Edge.

However, its file size is proportional to image size, and isn't supported by older browser like IE.

Loading Patterns

seamless repeatable patterns built for animation

Loading Patterns is loading.io's animated pattern generator that makes tiled images for using as texture, image pattern or in backgrounds of app, video or website. It can also be used to fill shapes, icons or progress bars.

Seamless Repeatable

All background patterns generated in loading.io are seamless repeatable, either in static or animated format.

This significantly reduces the size of animated image, and is perfect for looping as background tile in any place with variant size.

Vector-based Image

Tiles are all designed based on lossless vector image format SVG with the capability to generate to other formats including GIF, PNG/APNG and PNG sequence.

SVG format keeps the highest quality of images against resizing while also optimizes the file size and possibility for flexible retouching.

Animatable & Customizable

Loading.io empowers the background patterns with various types of animation which could be customized with loading.io's pattern editor.

All patterns are pre-designed but can still be customized according to your need.
