ABSTRACT:
From a climatic point of view, Romania differs from other geographical regions, the result
being specific microclimates favourable for vine cultivation. Our microclimate influences
cultivated vine sorts and the wine quality.
Analyzing climatic particularities of five wine-growing regions during 2006, from a
point of view of thermic resources, pluviometric conditions and climatic events, we can
conclude that, from a climatic point of view, 2006 was a favourable year for vine culture,
securing premises for a good production, in quantity as well as in quality.
Key-words: climate, vine, wine-growing regions, quality.
1.1 CLIMATIC CHARACTERIZATION
1.1.1. Wine-growing region Moldavian Hills (Dealurile Moldovei)
Climate particularities during 2006 and their consequences over vine plantations will be
presented based on specific time periods, analyzing critical climate factors having impact
over vegetation status and production potential.
From a thermic point of view, 2006 was a year warmer than usual, the medium
temperature oscillating between 8,6 and 11,4 0 C. 2006 started with a cold winter, even frosty
at night and in the morning. In January, the snow was set on most of the land, except the
south of the region, where its absence resulted in damages. The lowest temperature in
January was between –19,9 0 C and –26,8 0 C. As for the highest temperature, this was
between 31,4 0 C and 36,1 0 C, during August.
Analysing the rainfall amount, there has been concluded that, overall, in Moldavia was
recorded in 2006 a surplus of 7,3 l/m 2 than the average multi-annual amount. The highest
values were recorded in the north of the region, where the rainfall amount had a surplus of
19,2 % than the average multi-annual amount. At the other side is the Central-South of the
region, where the deficit was of 10%.
On a monthly basis, the rainfall amount during 2006 was higher from January to May,
except for February and June. The highest amount was in August, the surplus being of 99 %
over the average amount. The daily water quantities were in most of the places over 30
l/m 2 . The deficit of buds due to frost was of 11 – 15 % in the South and 20 – 35 % in the
North-Central region.
Over January, February and the beginning of March, the soil stayed frozen, with a
depth of 1-10 cm on most of the agricultural region, even 20-35 cm on some parts.
Summer was cold at the beginning, with high thermic amplitudes and a high haziness,
delaying the growth and development processes at all the sorts. All along the summer there
were reported rainfalls, mainly sudden showers, but also torrential. All over the region, on
small areas, stormy winds and hail storms partially affected the vine plantations.
Autumn started with a nice and warm weather, with few rainfalls. The end of autumn
and the beginning of winter (December, 2006) was marked by a high thermic regime and
few rainfalls. It is important to point out that in December 2006 there was no snow layers in
the region.
