1) Quite a number of the commentary states that allow cash for Christmas and it has already taken into account. Again, it must take into consideration that all estimates are based on models whose output becomes chaotic week, and a longer period. Thus, not considering the time scale. Thus, both could go, but not necessarily. For example, at 12 GFS model showed Eesti place was the center of the cyclone hit, which excludes cash at Christmas time. Next update might as well show the opposite picture again. What is certain, though at least a week of cold weather period (minima -25 ... -30 C).
2) Here we come to another comment, which ended with a cold will not go, because the sea off. The Baltic Sea is affected by the air mass when they come over the sea. When the continental air masses come by, it is after all, the sea, and therefore manfrotto geared head not affecting the mean sea off state anything other than the coastal areas and islands, and even when the wind is quite strong and the sea. The same opinion is also often in the spring - because the sea is cold, you can warm up to go. Yet virtually every spring warm waves arrived back in April, and sometimes in the past, when the sea ice just released or is still very little from the cold. Thus, the sea still can not prevent hot or cold air masses reaching. Mere has a significant impact on the islands and coastal areas, and even when the wind is quite strong, and the sea, the sea that are passed to the mainland. Few tens of miles inland from the sea, however, even a relatively manfrotto geared head small impact.
In summary, the Baltic Sea caused by local climatic differences, however, may be given without the impact will be negligible or absent, even in coastal areas where the wind is on the earth, or very weak. Also, Saaremaa manfrotto geared head and Hiiumaa, the inner part of the open sea, the situation was that the cold is over 20 C, but only a few coastal stations show risk of frost. So do not preclude the open sea is still very cold weather. This proves the following week.
Question of the upper image: if it is +5 .. +10 degrees tilt reaches the top, then how much should be warm? Comment on the bottom photos: 25 Dec.'s the difference between the degrees of 18 degrees. so - if allowed to +30 degree summer morning, then in the evening at +48 degrees for 22 ;). 17th December 2012 15:21
This is the 850 hPa temperature field. Since the summer surface warming is strong, it means there is a lot warmer near the surface, where 850 hPa level (usually taken from a standard 10 to 15 degrees). In the winter, especially in November and January, is dominated by cooling, which is why such logic can not be assumed. Thus, during the summer would be 0 C isotherm height of 850 hPa to warm the ground near 10-15 C, but during the winter can be a clear and calm weather, -5 ... -10 C (cooling and the resulting inversion! ), windy / cloudy 0 C but close. Even now, after all, was the 850 hPa height of the cold only 5-7 C, but the temperature near the surface was either the same or even lower, with only the islands was warmer. The top image: if it is cloudy and very windy, then it would be about the same as a warm, quiet and clear weather, or just above the black. manfrotto geared head A good example was the end of December last year, when the storm of air mass of cyclones has had the same amount of heat as a realistic measure of the ground: the warmer times of 5 .. 10 C. Bottom image: the kind of logic does not apply. During manfrotto geared head the winter season the temperature fluctuations manfrotto geared head can be much higher. It may be that changes daily temperature of 30 C (2003. JANUARY., T. Paljak wrote a thesis on such cases), but in the summer time, something like this will never happen. Even if there is no such day in July of 30 C, then, after the invasion of cold air, temperatures can fall more than 10-15 C, as well as warming - in some cases it is possible, for example, that in the morning is a warm 13-15 C, but in the afternoon With more than 30 C. What is spring or autumn half to go, the greater will be the temperature fluctuations. Thus, translating the projected volatility for July, summer morning would be +12 or +14 C, +30 C. However, in the afternoon You did well considering the fact that during the summer the sun we have here an important effect on the temperature of the winter, but now is not. Therefore, the summer temperatures are generally hästijälgitav daily visit to the cloudy day, but which are not currently in December. Thus, the translation should be projected manfrotto geared head into account that the maximum temperature in July is at 22, but still typically between 14-16, if there is a strong warm advection, may exceptionally be at 18 sites, while a clear morning, manfrotto geared head but the day is going to the cloud and sajule, then may already be at maximum around 10-12. 17th December 2012 18:43
In fact, the NAO index was strongly positive for some days, and the western stream of very powerful, it was noted, even with the advantage of ETV without notice. Should make themselves aware of what it means to NAO index - the pressure manfrotto geared head difference between the North Atlantic manfrotto geared head leading rõhkkondade, for more information manfrotto geared head see: http://ilmjainimesed.blogspot.com/2012/06/nao-indeksist.html manfrotto geared head So not cpc-s residues are
