Legend

The table gives data on the amount of precipitation in "lines" (tenths of a millimeter or tenths of a liter per square meter) in the left column, on the type of precipitation - in the middle column, and on the presence of snow cover and its height (in centimeters) – in the right column. When there is no number in the left data column, there is no precipitation. Climate stations report precipitation data every day. In case there is no information for a given date, n.a. is written in the middle column. Since 2021, the network of rain gauge stations at NIMH has been equipped with automated devices for real-time rainfall measurement, but the rain gauge stations continue to provide operational information of the 24-hour rainfall amount in the classic way once a day. Traditionally, it is only reported for days with measured precipitation ≥ 0.5 mm, but it is possible to have days with information for precipitation < 0.5 mm, and this is not wrong. For these stations, it is possible that there are days when there is precipitation, but no information is reported. For this type of station, an empty field means that no information has been received for the corresponding date. Also for this type of station information n.a. in all three columns means that wrong information has been received for that date and has been corrected.

Ground Surface Temperature

The ground surface temperature (also called “skin” temperature) is calculated for a grassy horizontal, flat ground surface outdoors with no horizon limitation. This is the temperature of the upper effective boundary of the grass or the exposed surface of the snow cover, if any. It is assumed that the grass surface is maintained in accordance with the recommendations of the World Meteorological Organization for the arrangement of a park for conducting meteorological measurements. It should be mowed at a height of several centimeters above the soil surface.

The temperature at a height of 5 cm above the soil surface is the closest temperature measured at a standard level to correspond to the temperature of the grassed ground surface.

The “skin” temperature is determined with a numerical thermal balance model constructed to use standard data of meteorological parameters: temperature and relative humidity of the air at a height of 2 m, wind speed at 10 m, amount of cloudiness, geographical location, date and time for solar radiation.

The sunlit land surface temperature can be much higher than the air temperature at 2 m, while the nighttime land surface temperature can be much lower in cloudless, dry and calm weather.

More about the Canadian Fire Weather Index

 

The system is operational since April,2008 during the warm months (April-October)The Canadian Fire Weather Index, FWI, developed in the Canadian Forest Service Research Center is used.

Data used (input elements for FWI calculation):

  • precipitaion amount for the last 24 hours;
  • air temperature;
  • air relative humidity;
  • wind speed; snow cover presence;
  • day duration.

FWI has three sub-indices showing the "dryness" of different types of "fuel". Each of these sub-idices is a complex function of the meteo-elements. Knowing the sub-indices and wind velocity data, two other sub indices are calculated, which evaluate the initial fire kindling and the available "fuel" for the further unfolding of the fire. On their basis the FWI in calculated and it gives an overall assessment of the intensity of fire unfolding (in energy released per unit time per unit length along the fire front line).

Thermal Comfort/Discomfort on the Bases of Feels Like Temperature

The proposed maps show the current or expected feeling of thermal comfort/discomfort of the majority of people. The maps refer to a standard time of day, which corresponds to the classical observation periods at weather stations. For example, 12 UTC (Coordinated Universal Time) corresponds to 14:00 Bulgarian time (15:00 summer time), which is usually close to the warmest hours of the day, and 03 UTC corresponds to 05:00 Bulgarian time (06:00 summer weather) which is usually close to the coldest hours of the day.

Thermal Comfort Classes, Description of the Sensation of Comfort/Discomfort and Recommended Clothing

The table shows the degrees of thermal comfort/discomfort. The categories of comfortable, warm and hot are defined on the basis of the degrees of physiological stress to which the human thermoregulatory system is subjected in the different temperature conditions according to the feels like temperature. The categories for cold are according to the Wind Chill Index.

Felt Temperature

Felt temperature is air temperature in a reference atmospheric environment where a person's sense of thermal comfort/discomfort would be the same as in real weather conditions. The feeling of thermal comfort is calculated using a full numerical model of thermal balance of the body of a "standard" human placed in atmospheric conditions near ground, outdoors, on grass or snow cover, if available. The feeling of thermal comfort/discomfort depends on the morphological parameters of the person - age, sex, height, weight and others, but for general purposes, the parameters of a "standard" person are used here. This is a 35-year-old man, 1.75 m tall, weighing 75 kg, in good health. The felt temperature depends on the work performed by the person and can be calculated at different power. In this case, it is assumed that the "standard" person performs work with applying the power corresponding to walking at a speed of 4 km/h on a horizontal surface. It is assumed that the wind always blows to the side of the direction of walking. The clothing is adapted (summer/winter) so that the "standard" person, if possible, achieves thermal comfort in the specific outdoor weather conditions. To determine the felt temperature, data on meteorological elements in the layer of air near the earth's surface (0–2 m), where the "standard" person is located, are used: air temperature; relative air humidity; wind speed; presence of snow cover. Also used: amount of cloud cover; geographical coordinates and altitude of the place; date and time.
