How do they determine the “feels like” temperatures for weather data?

Asked 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

What temperature do small meteorites have on impact

Asked by: Theresa Miller How hot is a meteorite impact? Entry into the atmosphere When they plow through the atmosphere, meteors are heated to more than 3000 degrees Fahrenheit, and they glow. Meteors are not heated by friction, as is commonly thought. A phenomenon called ram pressure is at work. A meteor compresses air in

Why are South African mountains short and flat?

Asked by: Theresa Miller These are a product of the glacial and geological history of the region. The flat hills are capped by hard, resistant dolerite. This is solidified lava that was forced between the horizontal strata of the sedimentary rocks (which make up most of the Karoos geology) through high pressure. Why are mountains

Why do cold-core lows slope towards the cold air with heigth? How to show mathematically that wind intensifies with height in this case?

Asked 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

Do northern lights (aurora borealis) show the same visual activity all along their visible latitude range?

Asked by: Alex Santiago What latitude are the northern lights visible? between 60 and 75 degrees of They usually occur between 60 and 75 degrees of latitude, which covers northern parts of Canada, Norway, Sweden, Finland, Alaska and Russia as well as all of Iceland. Can you see aurora borealis in other latitudes of the

Why does the Inter tropical Convergence Zone shift?

Asked by: Vanessa Martel The shifting of ITCZ is the result of the Earth’s rotation, axis inclination and the translation of Earth around the Sun. Seasons are the result of this. ITCZ moves toward the hemisphere with most heat, wich are either hemisphere summers. Why are the tropics shifting? Earth’s tropics are expanding poleward and
