Difference between snow, sleet, hail, rain, frost and dew

Here in Allentown , PA we have experienced either snow or rainfall everyday. This made me wonder how rain or snow or sleet or hail or dew and frost form? Did some Googling and here is what I got. Rain : Water vapor condenses around condensation nuclei (such as dust) and falls when the droplet is heavy enough. Sleet : Same formation as rain, but it freezes somewhere along its path from the clouds to the ground. Sleet is a mixture of snow and rain Snow : Water droplets form and then freezing occurs slowly, allowing for the development of uniquely designed ice crystals know as snow. Snow is formed when water vapour is deposited in the higher reaches of the atmosphere at a temperature less than zero degrees Centigrade, and then falls to the ground. Snowflakes are typically symmetrical, hexagon-ally-shaped groups of ice crystals that form while falling in and below clouds. Simply put - Snow forms if the air in a cloud is below freezing. The water vapour then turns to ice inst...

LCD guide

When I decided to buy a LCD TV (LCD = Liquid Crystal Display), I did a lot of online surveying. I am still yet to buy the TV but have been able to gather a lot of info. HD and HD ready The term HD (or full HD) refers to High Definition. HD offers an image resolution of 2 MP (Mega pixel) thats 1920x1080 pixels. HD ready TV is produces 1 MP images (1366x768 pixels). So obviously a full HD TV offers a better picture clarity compared to HD ready. HDMI High definition Multimedia Interface (HDMI)is almost the standard interface between home theatre systems and HD TV's. Usually a high bandwidth cable (capable of transmitting large amounts of uncompressed and digital data) is used to connect the HDMI port on the home theatre system or laptop to the TV. Check if your LCD TV has a HDMI port. Colors Check if the color reproduction of Red, Green and Blue is correct. Black should always be black! It should never be grey. Watch a colorful cartoon to see if there is no mixing of colors when the f...

US Presidential Election

Now that I am in this part of the world, I got an opportunity to find out how the President of the United States is elected.This what I found out. I just hope I have figured it out correct. Just a disclaimer: I have had very limited exposure to the US election process. So my interpretation may not be accurate. How is the US president elected? The US has an electoral college system established by the founding fathers as a compromise between election of the president by Congress and by popular vote. Under this system, citizens do not elect the president and vice president through a direct nationwide vote. US citizens vote for electors who will then vote for the president.The presidential election is decided by the combined results of all 51 states’ elections. Under the federal system of the US constitution, the nationwide popular vote has no legal significance, as it is the total electoral votes that determine the winner and not the nationwide popular vote. As a result, it is possibl...
