Meteorological has never been as accurate today – but how can scientists learn about the previous weather? In addition to environmental evidence such as ice cores and sediment, the historical records also provide unique in -depth information about the forgotten climate and the method of creating society while new research.
Researchers in Romania have analyzed historical records to create weather in the 16th century and the impact on society in Translvania. “Social storage” – including official documents, including personal writings such as chronicles and diary If there is details in the file study Published today in Bordering climateDocuments in the 16th century draw the cool image of the extreme weather and the consequences before starting to have a shameful small ice.
“We show that the climate is significantly marked with a period of drought, heat wave and severe rainfall and flooding.” Oria University in Romania, the participants, said in A, said the study said that in the study said that in the study said that the study said in the study, said in Study said border statement– “Studies demonstrate the complex interaction between the heat waves, float, flood, and the impact of agricultural culture, public health and social security, emphasizing the role of climate in making the history of human”
The historical site reports that the first half of the sixteenth century was hot and abnormal in Translvania.
“One message in the calculation comes from the historical documents described as the summer of 1540,” Caciora explained, “'The spring is dry and the river is just dropped. Livestock fell in the fields and thick air with despair while people gathered in the process of praying for rain. “He referred to the document. “This bright account reinforces the emotional dimension and spirit of life through the extreme climate”
In comparing the frequent rainfall in the second half of the last century, there were many floods, especially in 1590. The researchers observed that these intense meteorological swing were usually followed directly. Or indirectly with disasters, including an epidemic for 30 years, 23 years of starvation and invasion of grasshopper nine years.
“The city may bring infrastructure that is stubborn to flood or migrate to a more favorable area,” said Caciora, emphasizing that the special climate event affects the Translvania community. “Challenges may have technological innovations such as improved irrigation systems or storage facilities.”
However, overall, the document is witness the weather more often than the cold weather through the 16th century. This is even embarrassing. “A small ice age“The global heat dissipation period is about 1560 and the average temperature per year in the northern hemisphere at 1.1 degrees Fahrenheit (0.6 degrees Celsius).
“This makes us believe that the small ice age may appear later in this part of Europe.” Caciora added his team's assumptions about the delayed moments, supported by the temperature later or reducing the temperature.
However, the researchers observed some limitations about their methods. For example, due to the lack of conflicting records and testimony, they are not able to create a new meteorological form for 15 years of century. They also emphasize that Soley historical texts are representatives of the population of Translvania in the 16th century, a minority. In addition, the first report is a witness of the local experience only and may be the subjective of the author.
However, “Study of the climate from the permanent storage of society is extremely important. Natural proplaza analysis,” Caciora concluded in the Meteorological Prophet. Naturally can be used to create a weather phenomenon. Over the past, when there is no direct measurement “It gives human views as the center of the past climate.”
Study about the climate in the past affecting human history, can also provide in -depth information about how the future weather phenomena may determine the community in the future.
