Study Notes
Climatic Factors
- Geographic location significantly influences climate.
- Sunshine duration in Bulgaria is roughly 2000-2500 hours per year, with maximum in July and minimum in December.
- Air masses from the Atlantic Ocean influence Bulgaria's climate.
- Icelandic cyclones bring significant rainfall in May and June, primarily affecting northern Bulgaria.
- Mediterranean cyclones are responsible for autumn-winter precipitation in southern and southeastern Bulgaria.
- Azores and Eastern European anticyclones bring clear and dry weather.
- Relief, particularly mountain ranges, affects air masses, leading to precipitation on windward slopes and dry conditions on leeward slopes.
Climate Elements
-
Air temperature in Bulgaria varies, with the Sandanski-Kresna region having the highest average annual temperature (13.9-14.0°C).
-
Temperature decreases with altitude.
-
July is the warmest month, while January is the coldest.
-
Temperature inversions are common in valleys during winter, resulting in unusually low temperatures.
-
Average annual precipitation in Bulgaria is 670mm.
-
Flat and hilly areas receive 550-650mm, while mountainous regions receive 800-1000mm.
-
Rainfall is highest in May-June in northern Bulgaria and the high valleys of Western Bulgaria.
-
Southernmost regions and the southern Black Sea coast experience peak rainfall in November-December.
-
Precipitation decreases from west to east.
-
Snow cover varies in duration and thickness across Bulgaria.
-
Northern Bulgaria experiences snow cover for 50-70 days, while southern regions have sporadic snow cover.
-
High mountain areas have persistent snow cover for 7-8 months.
-
Dominant winds in Bulgaria blow from the west and northwest.
-
Mountainous regions experience higher wind speeds.
-
Northeasterly winds prevail along the Northern Black Sea and Dobruja during summer.
-
Local winds such as the gusty southerly "blow dryer" wind and the strong northerly "pine" wind occur during the warmer months, primarily on the slopes of mountains.
-
Breezes are characteristic of the Black Sea coast.
Climatic Regions
-
Bulgaria is divided into 5 climatic regions: temperate, continental, transitional, continental-Mediterranean, Black Sea, and mountainous.
-
The temperate continental climate area covers the Danube Plain, the Pre-Balkans, the Western and Central Stara Planina (up to 1000m), and mountain-basin areas like Kraishte.
-
Average January temperatures in this region are the lowest (-1 to -3°C), while mid-July temperatures are high (+22 to +24°C).
-
Temperature amplitudes range from 24 to 26°C.
-
Average annual rainfall is approximately 500-650mm in the lowlands; in the Stara Planina and Vitosha mountains, this increases to 1000mm.
-
Rainfall declines to 450mm in Dobruja (eastern Bulgaria).
