This is one of twelve antique wall maps of the world created by Justsu Pethes based on the data and scientific studies of Dr. Rudolf Geiger. As described within, the map focuses on the topic of mean air temperature throughout the world in which the data has been reduced to sea level. This way, the latitude, distortion of land and sea, ocean currents and air circulation become the dominating influence.
Since this map presents mean air temperatures in July, the higher temperature observed are shown in the northern hemisphere and is most apparent when comparing the polar regions. West and dry season are also depicted using dots and diagonal lines. Interesting observations to note include the hottest area of the world located in the western Sahara and the area of highest temperature variation being the western coast of the United States.
This map is of particular interest with regards to the topic of climate change as it provides a beautiful visualization of temperature in our world approximately 90 years ago.
Dr. Rudolph Geiger (1894 - 1981) was a German meteorologist and climatologist, who worked with Wladimir Peter Köppen and introduced some modifications to the Köppen climate classification, which is one of the most widely used climate classification systems back then and still to this day. It is now often referred to as the Köppen–Geiger climate classification system.
Condition: This wall map is in A condition with displaying beautiful colors on clean paper. It is still secured to its original rods which can be easily removed for framing purposes upon the request of the buyer.
