9月8日 的 Wet Bulb Temperature Tracker 應用程式分析

The number of high Wet Bulb temperature days is rising each year, and this free Wet Bulb Tracker keeps you informed for your health and safety, so you can plan your activities for the day, at work or with family. Wet Bulb Temperatures measure humid-heat conditions, not just air temperature. That temperature tells you how well your body can cool through sweat evaporation. With the Wet Bulb temperature, you can track how warm your body will get if you don't take steps to cool when outdoors and active. It helps stay safe from Heat Stress. We feel comfortable at typically 25°C / 77°F or below, whereas our core body temperature is around 35–36°C / 95–96.8°F. A Wet Bulb higher than 30°C / 86°F quickly feels uncomfortable as cooling through sweat becomes difficult. Though people in warmer climates are acclimatised to higher wet bulbs, as Wet Bulb temperatures approach body temperature, serious health risks emerge—especially for those active outdoors through work, play, or travel. Wet Bulb Tracker puts that number on your screen for wherever you are, right now and for the hours ahead. TWO RELATED READINGS FROM WEATHER DATA Wet Bulb is usually measured using physical instruments in the field, but is also approximated with math. • Wet Bulb — worked out from air temperature and humidity using Stull's formula. This is a convenient reference to get a general sense of the heat risk. • Wet Bulb Globe (WBGT) — is for outdoors, and also uses sun and wind in calculating heat risk. This is the one that matters if you're working, training, or walking outside. SEE A WHOLE DAY'S TIMELINE View an hourly timeline of each day's Wet Bulb temperature, coloured by safety level, showing how humid-heat builds and fades. Drag the marker across the day and the Wet Bulb and Weather readings above it change. Hours likely to see rain show a smaller bar in the block, giving the percentage chance of rain in your area. Rain and Wet Bulb can often be independent in how cool you feel. KNOW WHAT TO DO Every risk level comes with basic but handy Guidance: how long it's reasonable to stay out, what to watch for, and when to take breaks. Reference links in the About page cover the Wet Bulb thresholds used by militaries, occupational safety bodies, and national weather services around the world, with links to the underlying research. HEAT ALERTS Choose to enable Alerts. Get notified when outdoor conditions go higher, wherever you are. Silence alerts that would arrive between 10 PM and 7 AM, so you see them on the lock screen in the morning. WORK IT OUT - GET AN UNDERSTANDING The Calc tab lets you slide in any air temperature, humidity, wind speed, and solar radiation and watch both readings respond. Useful for teaching the concept or calculating from data.
