How do they determine the “feels like” temperatures for weather data?
Weather & ForecastsAsked by: Jami Olson We calculate a ‘feels like’ temperature by taking into account the expected air temperature, relative humidity and the strength of the wind at around 5 feet off the ground (the typical height of a human face!), combined with our understanding of how heat is lost from the human body during cold

Why do cold-core lows slope towards the cold air with heigth? How to show mathematically that wind intensifies with height in this case?
Weather & ForecastsAsked by: Alex Santiago Why does cold core low intensify with height? It is a low pressure system that strengthens with height in accordance with the thermal wind relationship. If a weak surface circulation forms in response to such a feature at subtropical latitudes of the eastern north Pacific or north Indian oceans, it is

Why a stratus cloud does not always reach all the way to the ground?
Weather & ForecastsAsked by: Buddy Perez Is stratus clouds found closer to the ground? Stratus clouds are low-level clouds close to the ground, so at times, stratus clouds appear fog-like and are even called ‘high fog. How far off the ground are stratus clouds? Found at very low levels (less than 2000 meters, or 6500 feet), stratus

Will global Warming continue to produce winter storms in the Northeast US?
Weather & ForecastsAsked by: Michael Christenson Climate models suggest that extreme snowfalls will become rarer, but not necessarily less intense, in the second half of the century, as more storms produce rain. The sharp increase in high-impact Northeast winter storms is an expected manifestation of a warming climate. How will global warming affect the Northeast? Climate change

Why does the frost depth increase when the surface temperature warms up?
Weather & ForecastsAsked by: Alyssa Lynn Why does frost go deeper when it warms up? That’s is due to the slow diffusion of heat into the ground. Unlike a liquid, pieces of soil can’t move around, therefore, in the absence of liquid water, heat can only be transferred by conduction, a process that follows the diffusion equations

Persistence time of ozone
Weather & ForecastsAsked by: Ruth Hamkens O3 has the shortest lifetime (τ = ~1 hour in urban atmosphere, McClurkin et al., 2013) among the three pollutants. The level of ozone is affected by its precursors (NO2 and VOCs), which both have large variability(Sharma et al., 2016). … How long can ozone molecules last? Ozone decomposition Temp (°C)
