What else can I help you with?
What tells you how fast the is blowing the wind is blowing?
The speed that the wind is blowing is typically measured with an instrument called an anemometer. An anemometer has rotating cups that spin faster as the wind speed increases. The rotation is then converted into a wind speed measurement.
What is a measure of cooling combining temperature and wind speed?
The measure of cooling combining temperature and wind speed is called the wind chill factor. It quantifies how cold it feels to the human body when exposed to a combination of cold temperatures and wind. The higher the wind speed and the lower the temperature, the lower the perceived temperature due to increased heat loss from the body.
Which of these terms refers to the day to day changes in temperature wind speed and precipitation?
Weather refers to the day-to-day changes in temperature, wind speed, and precipitation.
What is the wind chill temperature when the temperature is 20 degrees Fahrenheit and there is a 15 miles per hour wind?
-8 F
What does fronts always bring a change to in wind?
Fronts bring a change in wind direction and speed. As a front passes an area, the wind will shift in direction, and the speed may increase or decrease depending on the type of front (cold front, warm front, stationary front, or occluded front). These changes in wind are often accompanied by shifts in temperature and precipitation.
What increases cooling that a wind can cause is called the what?
The answer is.... Wind chill factor
Could it change a cricket's churp if the temperature increased and wind dropped?
Yes, an increase in temperature and a decrease in wind speed can cause a cricket to chirp more frequently. Crickets chirp faster in warmer temperatures because their metabolic rate increases, while lower wind speeds make it easier for them to produce sounds.
What is a measure of the heat loss from skin due to increased wind speed?
One measure is the wind chill index, which calculates how cold the air feels on exposed skin due to wind speed. As wind speed increases, it enhances heat loss from the skin, making the temperature feel colder than what a thermometer reads. The wind chill index takes into account both air temperature and wind speed to estimate this perceived temperature.
How is wind speed affected by altitude?
Wind speed generally increases with altitude. This is due to a decrease in surface friction and obstacles that slow down the wind closer to the ground. As air is less hindered by obstacles at higher altitudes, it can flow more freely and result in higher wind speeds.
What weather variable generally decreases when wind speed is increasing clouds are thickening and visibility drops?
When wind speed increases, clouds thicken, and visibility drops, the weather variable that generally decreases is temperature. This is often associated with the arrival of a cold front, where cooler air replaces warmer air, leading to a drop in temperature. Additionally, increased cloud cover can block sunlight, further contributing to a decrease in temperature.
What are the factors effecting evaporation?
Factors affecting evaporation include temperature (higher temperatures increase evaporation), humidity (lower humidity increases evaporation), surface area exposed to air, and wind speed (increased wind speed can enhance evaporation). Additionally, the presence of impurities in the liquid can also affect the rate of evaporation.
What type of weather results from a warm front moving into an area?
the wind speed decreases the temperature increases and nimbus cloudsappear
Does wind or moving air decrease the rate of evaporation?
No, it increases the rate.
Does water evaporate faster or slower in a morning?
It will evaporate faster when the temperature increases.
What impact does increasing wind-speed have on wind chill?
Increasing wind speed increases the rate of heat loss from the body, making the air feel colder than it actually is. This results in a lower perceived temperature, known as the wind chill effect. The higher the wind speed, the stronger the wind chill effect.
How is thrust related to the speed of an airplane?
As trust increases, speed increases. Providing the angle of attack, and the wind speed stay the same.
Do Tail wind increases the speed of the object?
yes
