※Hands-On Weather Study – Observation and Data
Forecasters have to understand current weather situation if they want to correctly forecast future weather. They have to rely on weather observation to achieve this goal.
Observer tracks cloud and weather situation, UV index, temperature, wind, rain and atmospheric pressure… meteorological elements. Thanks to these observers’ persistent efforts, we are able to receive weather forecast information right away. It makes our life more convenient and safe. |

Outside Temperature20.4 ℃
Outside temperature is more affected by the weather.
|
Inside Temperature24.8 ℃
Inside temperature is more affected by artificial causes.
|
Outside Humidity67%
Outside(Relative)humidity is often used in weather forecast.
|
Dew Point14.1 ℃
The higher the relative humidity, dew point is closer to temperature.
|
Heat Index
20.5 ℃
Is an index that combines air temperature and relative humidity to posit a human-perceived equivalent temperature──as how hot it would feel.
|
Wind Chill
19.2 ℃
A kind of surface temperature due to the chilling effect of the wind on the skin. The air feels colder than the reading.
|
Temperature-Humidity-Wind Index
19.3 ℃
The temperature perceived by human, caused by the combined effects of air temperature, wind speed and relative humidity.

Atmospheric Pressure |
Air Density |
UV Index |
Solar Radiation |
1018.1 hPa
Is closely approximated by the hydrostatic pressure caused by the weight of air above the measurement point. It is caused by gravitational attraction of the planet. It is the pressure within the atmosphere of Earth.
|
Air Density
1.1899 Air density is the mass per unit volume of Earth’s atmosphere under specific temperature and atmospheric pressure.
|
UV Index 2.0
Ultraviolet index is an international standard measurement of the strength of sunburn-producing ultraviolet radiation at a particular time and place.
|
311 W/m2
With solar radiation, we can know about the energy absorbed by earth surface, to further understand the level of greenhouse effect.
