Weather conditions in 2000

In addition to the many reviews of the year 2000, there should also be a review of the weather. How was the weather last year - who remembers? To anticipate: The year 2000 was the warmest year since the weather records began, with an average temperature of plus 9.8 degrees Celsius.

In Balingen-Heselwangen (573 meters above sea level), the seat of the meteorological station, observations have been made on the temperature profile and precipitation profile since 1979 and for sunshine since 1990. According to this, the average for the previous 21 years (1979-1999) was 8.3 degrees Celsius over the year and precipitation (rain, snow, hail, etc.) averaged around 900 liters (exactly 886.4 liters) for each person Square meters of ground at the measuring station. On average between 1990 and 1999, the sun shone over the district for 1,761.3 hours. In contrast, the year 2000 shows an annual average temperature of 9.8 degrees Celsius and a total rainfall of 845.2 liters per square meter. In the year 1763, which has just ended, the sun shone for 7 hours. Compared with the mean values ​​from previous years, the clouds from 2000 did not quite achieve the target precipitation, the duration of sunshine was pretty much the mean value - but the temperature, on the other hand, is noticeably too high and must make you think.

In the representation of the weather elements temperature, precipitation and sunshine in the form of a graphic, it is evident that in 2000 ten out of 12 months were too warm. Only January and July were a bit colder than usual. In contrast, February, April, June, November and December in particular were significantly warmer. The differences in the distribution of precipitation over the year can also be seen very clearly. Half of the months of the year were too humid and the other half too dry. June and December were particularly dry. June also holds the record for hours of sunshine. 285.1 hours versus the average of 196.9 hours. Even the sunny summer months of July and August fade away with 198.2 and 241.7 hours in 2000, respectively.

But what were the special weather phenomena in the individual months of 2000?

The values ​​in brackets indicate the monthly averages or monthly sums in the order: temperature / precipitation / sunshine duration in hours.

January: Looking back, the winter of 99/00 disappointed at the beginning of the year. A thin, perforated blanket of snow covered our district area. Around "Holy Three Kings" it was up to plus 10.5 degrees. Inversion weather conditions around the middle of the month brought sunshine to high-lying areas, while fog in the valleys. Frau Holle only shook her beds more vigorously in the last third of the month and Father Frost joined them. Minus 18.3 degrees Celsius were registered on Tuesday, January 25th.
(- 0.5 C / 36.0 liters / m² / 78.2 hours)

February: There was a closed snow cover only on four out of 29 days in February. There was also no ice day (all day below zero degrees) registered. But it rained 22 out of 29 days. At the end of the month the temperature rose to 17.3 degrees. Conclusion: The winter of 99/00 wasn't one.
(+ 3.9 C / 73.1 liters / m² / 79.2 hours)

March: A February that was too mild was followed by a March that was too mild. There were no crisp cold days at all in this month. At the beginning of astronomical spring (March 22nd) it was warmest at 17.7 degrees. On March 30th, the snowfall ended and winter said goodbye in lower elevations.
(+ 4.5 C / 78.0 liters / m² / 110.7 hours)

April: There were already three summer days (= <25 C) this month. Summer days are a rarity in a spring month. The four other registered frost days were all in the first third of the month. After moderate weather in the middle of the month, the Easter Bunny started sweating on Easter Saturday, April 22nd. The thermometer showed 25.9 ° Celsius as the maximum temperature on that day.
(+ 9.9 C / 48.1 liters / m² / 173.3 hours)

May: May was in reverse order to April. First summer heat with up to 27.6 degrees (May 11th) and "sweat saints" instead of "ice saints". But then the month changed its mind again and swung to "normal" values, only to say goodbye to June relatively cool. Tuesday, May 30th, was a special day. By then, May was below its precipitation target. But on that day a heavy rain area crossed Baden-Württemberg and dropped 64.1 liters on every square meter at the measuring point. Conclusion: The spring of 2000, as well as its individual months, was clearly too warm.
(+ 14.0 C / 135.5 liters / m² / 198.5 hours)

June: June was an extraordinary month in terms of weather - and this, both in terms of temperatures, as well as the duration of sunshine and lack of precipitation: this month has the highest value in everything - and this in turn at least since the beginning of the regular weather records for Balingen in the year 1979. With an average temperature of 17.5 degrees, June 2000 was 2.6 degrees warmer than its average (from 1979-1999) and with only 20 liters of rain per square meter, 86.7 liters drier than usual. A sunshine duration of 285.1 hours contributed to these records, which is also 88.2 hours above the average of 196.9 hours. The first "hot day (=> 30 degrees) was on Monday, June 19, with 31.1 degrees. One day later (shortly before the astronomical start of summer) the highest temperature of the whole year was registered with 32.3 degrees."
(+ 17.5 C / 20.0 liters / m² / 285.1 hours)

July: After five consecutive months that were too warm, July stepped out of line. Overall, this month was too cold, too wet and too dark. Starting difficulties in the summer began shortly after the beginning of the month. In total, it rained 21 days out of 31.
(+ 15.3 C / 118.8 liters / m² / 198.2 hours)

August: What July missed in the summer of 2000, August made up for it. Finally the children could go swimming with us during the holiday month. Nevertheless: Due to some heavy downpours, the precipitation target for this month was exceeded. Conclusion: Despite a cool and rainy July, the summer of 2000 was slightly better than the average.
(+ 18.1 C / 104.7 liters / m² / 241.7 hours)

September: The meteorological autumn days begin with September. This year it was really autumnal. Even so, this month was a bit warmer than usual. But September only got the warmth around the middle of the month. Before and after, he literally fell into the water. Often there was more than nine hours of sunshine a day, which then gave the apples and pears, which were plentiful this year, a boost of sweetness.
(+ 14.0 C / 98.2 liters / m² / 165.8 hours)

October: There was no golden October 2000. Nevertheless, this month was again too warm. But it also brought the first frost (October 8th) after summer. Apart from the excess temperature, the month was overall too dry and too dark.
(+ 9.9 C / 55.5 liters / m² / 85.8 hours)

November: November was felt more like spring than winter. The monthly mean was around three degrees above its mean, and the warmest day was measured at 15.6 degrees on the last day of the month. At the beginning of the month a storm swept across Western Europe, which largely spared us. Although there were 10 rainy days in November, the month overall was drier than usual. Conclusion: autumn was too warm.
(+ 6.2 C / 48.9 liters / m² / 80.9 hours)

December: Even if December was winterly cold towards the end of the month and even put on a thin white dress, this does not hide the fact that, overall, December was only a winter month according to the calendar. With a monthly mean temperature of plus 4.4 degrees Celsius, December was 3.2 degrees too warm compared to the average for the years 1979-1999, making it the warmest December in this period. December got the warmth plus from the beginning of the month. The first 10 days of the month were on average twelve degrees at a maximum and 3.6 degrees at a minimum. After the middle of the month it got colder, and after a brief rearing up, the first ice day (all day below zero) was registered at the astronomical beginning of winter (December 21). In the days that followed, we went even further into the cellar (but only at night). The minimum thermometer showed minus 8.4 ° C in the early hours of the day before "Christmas Eve". Christmas, on the other hand, was again green and rainy on Christmas Day. Some snow fell in the last days of December.
(+ 4.4 C / 28.4 liters / m² / 66.3 hours)

The year 2000 in weather statistics

The values ​​in brackets indicate the average values ​​from the years 1979 - 1999 or refer to the specified year.

The annual mean temperature in 2000 was 9.8 (8.3) degrees Celsius and 845.2 (886.4) liters of precipitation fell on every square meter at the measuring point. In total, the past year had 138 (129.1) rainy days, these are days on which it rained or snowed one and more than one liter per square meter. The largest amount of rain within 24 hours fell on May 30th with 64.1 liters / square meter. During the year, the wind picked up on 97 (104) days up to at least wind force six (39 km / h and more), and local or distant thunderstorms were recorded on 24 (26.1) days. Fog only existed on 15 (34.0) days and the sun shone at the observation site for 1763.7 hours. The average for the previous ten years was 1,761.3 hours. After a careful extrapolation, however, around 50 hours can be added to the annual total that are missing at the station because the sunrise at the station is delayed or the sunset occurs earlier due to the shadows of the mountains, neighboring houses and trees.
There were frost on 66 (102.1) days in 2000 and ice days on which it remained below zero all day, only 7 (21.9) were counted. By the way, the coldest day of the whole year 2000 was Tuesday January 25th, with minus 18.3 (-16.0) degrees Celsius and the frost-free time lasted from April 9th ​​to October 7th - that is 182 (165.0) days . It only snowed on 21 (41.0) days and a closed snow cover was also only on 20 (39.9) days. If you add up all the snow that has fallen, you get a total of 26 cm (89.1) cm of fresh snow. - in 1999 a proud 182 cm. In 2000, the thickest snow cover was at station height on January 24 with a meager 13 cm.
Summer days (25.0 and more degrees) came together 46 (39.1), of which April contributed 3, May 5, June 13, July only 5, August 16 and September 4. Hot days (30.0 and more degrees) were counted 8 (5.9), of which August alone can boast 4.
