Which of the six colors of the rainbow is refracted the greatest?
The color of the rainbow which is refracted most is violet.
What is a mirage and why does it always disappear as the observer gets closer?
Mirage is a visual occurrence in which rays of light are bent to fabricate a displaced picture of far-away objects. Light from a far-away thump a thin 'sheet' of hot atmosphere just above the roadway or desert sand acting as a mirror and imitate an object at an equally tiny angle of your eye whereas you are still at a distance.
If you were looking for a rainbow in the morning, which direction (N, S, E, W) would you face and why?
A rainbow in the morning signifies that there is a rain west of us and it will possibly come to our location, while the sun is in the East.
What is a halo?
A halo is a slim circle of light that occasionally emerges around the Moon and the Sun. it is formed by refraction of light as it passes through a hexagonal ice crystals high in the sky.
Why is the sky blue?
The sky is blue because of the mode the light disperses and stirs in the atmosphere.
Why are sunrises and sunsets red/orange?
Sunset have a red/orange colour because the sunshine is made up of all different colors of light and each have different wavelength; during the period of a sunset, its rays have to overcome a much larger layer of the atmosphere than when the sun is at its zenith. Due to the fact that the red light scatters less than the light of any other color, it almost easily passes the layer of the atmosphere, while all the other colors of the spectrum scatter passing through the thickness of the air space of the Earth so much, that they actually can not be seen.
Why are clouds white?
Clouds consist of an ice crystals and water droplets. These dewdrops and crystals are bulky enough to disperse the light uniformly. Because the light of all the wavelangths is scattered equally the light remains white and hence that's what makes clouds look white.
What is the basis for the classification of clouds and why?
Clouds are classified according to their height above and appearance from the ground.
Why are high clouds always thin in comparison to low clouds?
Hihg clouds are always thin, because they are far away and the air in the upper atmosphere is less dense and wind can be high too.
What is a condensation nucleus and why is it important?
Condensation nuclei are small essentials of atmospheric contamination, which provide surfaces for condensation of water. Condensation nuclei are important because with no dust, salt or smoke that make up condensation nuclei there can be no condensation.
How does hail form?
The hail is formed when thunderstorm updrafts are strong enough to hold droplets above the freezing level. Freezing forms a hailstone, the hailstone is too heavy for the updrafts to hold it and it falls to the ground.
What is the difference between clouds and fog?
Fog is a cloud attached to the ground. It differs from all other clouds as the fog touches the surface of the Earth while the clouds are an observable mass of reduced droplets or ice crystals suspended in the air above the surface of the Earth.
If you see towering puffy clouds in the afternoon, you are probably seeing what kind of cloud? What does this mean for the weather forecast this afternoon and early evening?
Puffy cloud is also known as cumulus cloud and it always indicates fair weather during the noon and evening hours.
What is a weather satellite and how does it help us make forecasts?
A weather satellite is a satellite used by meteorologists to collect information about the weather. It informs meteorologists on how clouds will vary, and forecasts the weather, be it rain or shine, for many regions.
How do computers help weather forecasting? Can we just let the computer tell us what the weather will be without human intervention?
In meteorology computer helps to predict the weather analyzing the atmosphere by tracking the changes in the atmosphere and charting them. The computer can scrutinize the information and produce a prediction. And without human intervention in weather forecasting the disasters such as tsunami, drought and other natural calamities can be left unpredicted and bring a lot of harm to unprepared people.
What is an ensemble and how does it help us tell what is coming up in the weather (or accuracy of our forecast)?
Ensemble forecasting is a statistical prediction system that is used to attempt to create a representative section of the possible potential states of a dynamical system. Ensemble forecasts give an observation of the improbability in the essential information, and are appropriate for quantitative use in concurrent decision making.
What is weather radar? How does Doppler radar differ and how is it the same as old-fashioned weather radar?
Weather radar, is a sort of a radar used to measure the precipitation, calculate its motion, and estimate its type. The Doppler radar differs as earliest radars were unsuccessful to operate as expected. Reason was sketched to Doppler upshots that demean performance of systems not intended for version for moving objects. Both dropplers use same working mechanism.
How do vertical profilers help us understand the weather?
The vertical profiler helps in measuring hourly profiles of wind speed and trend. The system helps to forecast the future weather pattern.
What is a microburst? Why is it dangerous and how do vertical profilers help us see them happening?
A microburst is an intense downdraft that falls down to the ground due to strong wind divergence. A microburst can cause the destruction of the above land utilities. Profilers measure the wind speed hence make it easy to counter an attack before it causes damages.
What is the practical limit for accurate precipitation forecasts?
The practical limit for an accurate precipitation is between 6-10 days.
