Now lets view its feather in detail:
1.Location place: city and country. It can not detect weather in America but also in Europe
2.Date: time, date, month, weekend, year
3.Weather conditions: Sun or cloudy or rain etc; temperature and and chill; barometer; humidity; sunrise time and sunset time.
4.Forecast in the next two days: weather condition, the high temperature and the low temperature.
5.You can choose "enable severe weather alerts based on current device location" or not.
6.The weather condition can be expressed by a vivid picture on the right corner of the opening page.
Weather is the state of the atmosphere, about the degree that it is hot or cold, ,clear or cloudy,wet or dry, calm or stormy. Most weather phenomena occurs in the troposphere, just under the stratosphere. Weather generally refers to day-to-day temperature and precipitation activity, whereas climate is the term for the average atmospheric states over a longer periods of time. When it is used without qualification, "weather" also is understood to be the weather of Earth.
Weather is driven by denseness (temperature and moisture) differences between one place and another place. These differences can occur due to the sun angle at any particular spots, which varies with latitude from the tropics. The strong temperature contrast between polar and tropical air gives rise to the jet stream. Weather systems in the mid-latitudes, such as extra tropical cyclones, are caused by instabilities of the jet stream flow. Because the Earth's axis is tilted relative to its orbital plane, sunlight is incident at different angles at different times of the year. On Earth's surface, temperatures usually range ±40 °C (100 °F to −40 °F) annually. Over thousands of years, changes in Earth's orbit affect the amount and distribution of solar energy received by the Earth and influence long-term climate and global climate change.
