How to prepare a family for a hurricane?

in

Hurricane Sandy is heading our way, and my whole family (especially my children) are scared. We have the basics: flashlights, batteries, and some packaged food. That's about it. Our local store is closed and sold out of pretty much everything. I have a two month old baby, and I was thinking about buying a bunch of milk, but then decided not to because if the power went out, it would all go bad. We've also gone over some basic hurricane safety, just in case.
What are some more things we could do to prepare for the hurricane?!

Answer: 
A basic emergency supply kit could include the following recommended items: Water, one gallon of water per person per day for at least three days, for drinking and sanitation Food, at least a three-day supply of non-perishable food Battery-powered or hand crank radio and a NOAA Weather Radio with tone alert and extra batteries for both Flashlight and extra batteries First aid kit Whistle to signal for help Dust mask to help filter contaminated air and plastic sheeting and duct tape to shelter-in-place Moist towelettes, garbage bags and plastic ties for personal sanitation Wrench or pliers to turn off utilities Manual can opener for food Local maps Cell phone with chargers, inverter or solar charger

How to know if there is tornado forming?

in

Okay so it is storming really bad right now and bad lighting and I the clouds are kinda Clustering together Is there any way of there's a tornado forming. Oh and there is a weather alert.

Answer: 
From the Storm Prediction Center: Strong, persistent rotation in the cloud base. Whirling dust or debris on the ground under a cloud base -- tornadoes sometimes have no funnel! Hail or heavy rain followed by either dead calm or a fast, intense wind shift. Many tornadoes are wrapped in heavy precipitation and can't be seen. Day or night - Loud, continuous roar or rumble, which doesn't fade in a few seconds like thunder. Night - Small, bright, blue-green to white flashes at ground level near a thunderstorm (as opposed to silvery lightning up in the clouds). These mean power lines are being snapped by very strong wind, maybe a tornado. Night - Persistent lowering from the cloud base, illuminated or silhouetted by lightning -- especially if it is on the ground or there is a blue-green-white power flash underneath.

How to average mean wave direction along time?

in

hi

I have time series of mean wave direction output from a wave model (wavewatch III). Data is for one year and I need average them to get annual mean. for averaging the directional data, they have to be split to meridional and zonal components and averaged and then recombine them. I don't know wwhetherthe data is in polar coordinate or not and do I need to convert the ccoordinate
I want to use matlab to do that.
any help is highly appreciated.

Answer: 
Hello! You used very big words that I did not understand so I'm sorry if this is not what you..... MEAN! ( get it mean, you want the mean) ok joke times over ( I know I'm pathetic) so if you have coordinates than tally all the coordinates type all them in on a calculator divide them by 365 ( not on leap years) and you get the mean. =D ik I was no help but I tried :) if I didn't try I wouldn't be doing this trying is importent :{

How to find the nighttime temperature for Carson City on March 17 2012?

how to describe climate and weather for a park or region?

in

I'm doing a Bio project on Great Basin and it says to describe or discuss the climate and weather. I'm a bit confused. How do you describe or discuss climate and weather? Examples? Thanks!

Answer: 
Perhaps one of the best descriptions when defining weather and climate is that “climate is what you expect, weather is what you get”. A climate is really nothing more than the weather averaged over a long period of time, usually a minimum of 30 years. So for example, the climate of a region for September could tell us that the typical daytime highs are 20°C, the nighttime lows are 10°C, 100mm of rain can be expected during the month, 200 hours of sunshine, it’s misty twice, foggy once and the wind is usually from the south. If you were to observe conditions in that region each September for many years this is what you would get as an average. But it’s not what you would get on a daily basis, what you’d get day to day is the weather and this could be quite different. The weather is much more short-term and is influenced by a number of factors. It could be that one day the temp reaches 30°C, next day it’s 25°C, then 18°C then back up to 30°C. It might not rain for weeks or it could rain every day for a week, it all depends on what’s happening at that particular point in time.

How to drive out the excess heat from the equator?

in

If giant sunshades were installed on the roofs of every building in the city, would it help to radiate the excess heat back into space to prevent overheating ?

thanks
Please suggest an alternative.....like an atmospheric dehumidifier.
So how to make it ''not kept''by the atmosphere.
there are two factors here, heat and moisture.

Answer: 
A white sunshade would reflect infra-red radiation and that would reduce the heating effect of the sun. What it cannot do is prevent warm air heated up elsewhere, blowing into the area. So the overall effect is small.

How to create high pressure systems in the tropics by increasing the atmospheric pressure?

in

And decrease the high pressure in the polar regions so as to reduce the pressure differences between the two regions , so we get less droughts, more rain at the poles and less floods and cyclones at the equator. So we can reduce the extremities.

Any suggestions?

Thanks

Answer: 
Jon, when the sun appears between two clouds and you feel its warmth on your face, do you realize how much energy it is giving to the earth and what is needed to change its distribution? And even if we could, do you realize that each form of life on earth is adapted to its present climate and that, any change in the climate would mean tremendous change in the flora and fauna on earth? During the cultural revolution, chairman Mao decided that birds eating corn should be killed in order to get better harvests. Many birds were killed and the next harvest was the most disastrous of all because it was destroyed by ... the insects the birds were also eating! Don't rock the ship of nature, my friend! ;-)

How to walk in winter without getting muddy snow on my pants?

in

So it's winter and it snows a lot here. Sidewalks are cleaned, salted fairly often but there is always some muddy snow on the ground. When I walk, I somehow always get the muddy snow on my jeans around the back of my legs (lower calf areas). I even put my jeans inside my boots. Is there a technique that I have yet to perfect in walking? My friends don't seem to get as much mud on their pants. Please help!

Answer: 
Hmm.Sounds like a mess. I remember the slushy streets in NJ. I don't know if there is a special technique. Perhaps you could watch your friends closer.

How to stay cool inside when the humidity is horrible outside?

in

Right now I heard we have around 85% humidity, and the air is so thick you could cut it with a knife! I was wondering how can we stay cool inside? It's stuffy and hot, but not nearly as stuffy as outside. Should I leave the windows open to get a breeze/circulation, or would it just let more humidity in and make it worse? Alo which way are ceiling fans supposed to turn in the summer?
Did I say anything about drugs? Morons!

Answer: 
Well, here in Texas everyone pretty much uses air conditioning in the summer. You don't say where you live, but I can't imagine a summer here without a/c. If you don't have one, I think Grace has a good idea with the ice water. I just went and looked at my ceiling fan and it is turning clockwise if you are looking up at it. I know if we open windows here when it's humid, it just seems to make it more uncomfortable inside. But I guess if you don't have a/c, you have to open them. Just get as many fans as you can. (I have no idea why these people think you asked something about drugs!)
