  3. So they work in conjunction not far fetched at all but from what I have been hearing we seem to have this "blanket", if you will, setting up in the upper atmosphere, troposphere I would assume, wouldn't necessarily the whole column of air increase in temp or is it one of those functions where we see drastic increases in surface in conjunction with water vapor that help warm but the upper layers may tend to cool? I know as you go up in the atmosphere it's not necessarily feel temperature as you would experience at the surface it's more of energy based heat that jostle the molecules,so as if you were up in the Stratosphere it would fridged to our real feel skin but warm us on the inside, right? I'm just really curious about this topic and with only my knowledge of undergrad meteorology I'm trying to grasp these ideas and understand them without trying to be persuaded to one side or the other as it seems to be in many cases, rather try and figure this out and then down the road we can play the blame game.
  4. Also one more thing to add but when I was taking this class the water cycle and it's association in the atmosphere was not detailed very much as we have seen with co2 in class. Is this because water vapor has a really short tau in the atmosphere or is it because it's just not well understood as its longer lasting friend co2? I know we as humans have thrown a huge monkey wrench into the water cycle that surely needs to be corrected unless the atmosphere decides it wants to correct itself, which may just be happening as we speak about this topic.
  5. I mean I get the whole idea that co2 traps heat but how come nobody mentions the idea of water vapor trapping much of this at the surface and water vapor is in fact a much stronger ghg then co2 but since co2 lasts longer in the atmosphere we relate it to havingredients a much stronger forcing,if you will? I know water vapor in the atmosphere tends to have a lower time it resides in the atmosphere but can also be replenished just as quickly by similar processes. The thing that gets me is that with constant low level moisture stream you tend to have warmer muddled temperatures,coastal communities for example, but when we do not have moisture content as large say at night we have our diurnal swing when we have a true diurnal swing around here its not quite as noticeable of a temp change as one may think over time. Could our exuberant temperatures be due increases in low level water vapor in the atmosphere which willing turn have a feed back on melting and warming locations which will then set off a feedback process from that disturbance. I know it may another oversimplification but from my climate change class I took as a BS undergrad they pointed this process out that a slight change in one feedback can alter another feedback and alter another to create a positive feedback loop that can eventually turn maybe into a run away train type of ordeal until one day it hits a tipping point. Personally I just have a hard time conceptualizing the idea of how a doubling of co2, which has not occurred just yet currently at 400ppm average, in the atmosphere will increase temperatures such in a drastic pace as we have seen over the past 50to 75 years before this it seemed fairly consistent with time and with variations on either side and know we are really taking off. This is maybe more of a local idea but I know one thing for sure that temps alone can't really do too much to melt snow but add moisture into the mix even at a temp of say 34 and you have a totally different scenario sometimes down this way we have seen rapid melt occur from a temp such as that with a strong moisture Flux into the region. So something is telling me it is not all co2 but that co2 may be adding into the equation of our changing climate.
  6. The thing that bugs me on this is not everyone is gullible in the younger generation, it's whether people are willing to put the effort into understanding something and actually discerning truth from prophetic talk. So in a sense you can apply this same talk to every generation as to whether they want to believe this is in fact truth or something to question or something they are misguided with. I do not like how many teachers and professors feel as though it is their duty to incorporate their personal beliefs into discussion and teachings. Also one thing I would like to add for sure that I do not think anyone can deny while we have been seeing records for warmth I feel the majority of the records have been for overnight temps in many many locations we have been well above average I'm not sure exactly if this is the case for other locations but around here it has been due to overnight cloudiness and low level moisture increase. It may just be due to change in weather patterns allowing such to occur but when we have dayseen like today where we reached about 62 but our low stays at about 58 the high is about 8 degrees below average while the lows are about 10 to 12 above average in the region. That's huge because if you can not release the heat from the daytime due to low level residual moisture holding temps up then the next day we already make a run to higher temps and thus the process continues until the pattern breaks. This might be over simplifying something but many of our records occur during fall and winter versus spring and summer around here.
  7. I have been looking to get myself a decent camera but dont feel like spending an arm and a leg to get one. I have heard SLR and 10 megapixel is what to go for but havent really gotten much further from that info. I would like to be able to take a picture and have it come out crisp with clouds being able to see the intricate details without losing much of the surrounding. Any help would be great and if for some reason there are no responses Ill ask in a different thread. Thanks
  8. Hahaha this is too funny
  9. I usually go from the top of the BL, usually but not always ends up being around 850mb (1.5km). Take the temp at this level and dry adiabatically take it to surface it really depends on the conditions below as to whether a place will fully mix and reach max temp or whether to keep it down a bit. I like the idea from isohume: Ill have to give this a try and see how it works. Nashville was a pain for sure. My biggest issue I know at times was the low temperatures in places have to get better with forecasting for that and winds I tend to go a little too high on some forecast days.
  10. oh man i completely forgot about this I havent had much time to go online lately and just got the chance to log on here. Oh well off to may, one month cant hurt too much right?
  11. For finding average U and V you want to average the two layers. So Surface had (0,10) and 850 had (10,17) you just add the U together and divide by 2 since there are only 2 and do the same with V and should get (5,13.5). They did calculations for figuring out C vector, storm motion vector, within the hodograph. If you then subtract the C from U and V average you should get those values for each Usr and Vsr in sfc to 850 and then again 850 to 700mb. C is determined through the drawing of the hodograph and is approximated if being hand drawn. They didnt show how they got C so that doesnt really help seeing it through PPT but they mention it just underneath I believe what they found as their mean wind for storm motion. Now remember that 300 degree and 22.5 is a vector that should be broken down into its components just as your answer was given to you. That should do the trick.

  13. DCAPE SRH As for Effective BWD ----> I assume this is meant to be bulk wind difference? I never actually learned how to do so. But I believe instead of taking it say from 0-6km for bulk shear it takes it through the whole thunderstorm up to the EL. but feel there is more to it than just that.
  14. Really they chose Bismarck,ND over poughkeepsie, NY really and with this storm on the east coast that was the best decision! What is with these voters lol
  15. I saw right at the end of posting it still recorded 27 after 6z. Oh well not much of an adventure outside of guessing the right winds peed. Boring onto the next.
