操作系统和网络技术研究
pop：因为国内气象最高水平也就是预报未来三天，所以我只能给大家讲解一下08年“十·一”国庆节 可能出现的天气。
随着冷空气东移南下影响，未来几天里，内蒙古大部、西北地区东部、东北、华北、黄淮、江淮以及江南等地将先后有4～8℃的降温，局地降温可达10℃。
受冷暖空气的共同影响，未来几天里，青藏高原大部有小到中雨（雪）或雨夹雪；新疆西部、西北地区中东部、内蒙古西部偏南和东北部的部分地区、黑龙江大部、吉林东北部、华北南部、黄淮、江淮、江汉、华南、西南地区等地有小到中雨，其中，四川东部、浙江北部等地的部分地区有大雨，上述部分地区并将有短时雷雨大风等强对流天气。
在十一期间全国各大城市旅游景点天气基本上都会转凉，气温如武汉会从35度下降到25多左右，所以说今年“十·一”是一个出游的好时机；要是到沿海一带的话就要注意第14号强台风“黑格比”了。
这里这是我的一个预测，请大家以国家气象局为准。

AccuWeather
http://wwwa.accuweather.com/partner-signup.asp
AccuWeather now has a simplified interface to obtain weather "stickers," which does not require registration. The code they provide uses a linked javascript. The stickers are available in nine sizes, from 120x60 to 630x440, with a wide variety of background colors or images.
Weather Underground
http://www.wunderground.com/about/faq/weathersticker.asp
Weather Underground offers free current conditions boxes, with no registration required. Their site looks a little clunky compared to AccuWeather, the Weather Guys, or Intellicast, but their "sticker" for your website looks pretty good. The code they provide is a comparative lengthy table--which leaves you some possiblities in rearranging it if you are so inclined.
The Weather Channel
http://www.weather.com/services/oap.html
Probably better looking than the Weather Underground free weather, but not as quick to obtain, requiring registration. The code they provide is a short piece of javascript.
Intellicast
http://www.intellicast.com/About/IntellicastOnYourSite/FreeContent/
Intellicast offers a nice current conditions box, and a number of other free products. They now require registration. Their code is in the form of an inline frame. When I obtained a current conditions box, the code read HEIGHT="204" WIDTH="304" but the actual size of the box is 172x244, so you might need to adjust these parameters.
Intellicast offers current US national and regional current radar maps in a thumbnail image-- but it is very small (140x90), and the link cannot be set to open in a new window.
Time and Weather
http://www.timeandweather.com/
Time and Weather, from OnYourSite.com, supplies ticker which displays the current time and weather conditions in any of over 125 world nations. They used to supply a java applet, but now they provide an insert that requires that you have PHP running on your server, which, of course, almost all web hosts do.
