Although deep-sea and ice cores show a cool MIS-13 interglacial with low greenhouse gas concentration, proxy records mainly from Asia show a very strong monsoon at that time. LOVECLIM (the Earth Model of Intermediate Complexity of Louvain-la-Neuve) will be used to analyze this paradox. MIS-13 actually shows two main peaks dating approximately 485 kyr BP (MIS-13.11) and 501 kyr BP (MIS-13.13). The model is therefore forced with the appropriate astronomically-induced insolations, greenhouse gas concentrations and ice sheets at 495 kyr BP (northern Hemisphere summer at aphelion) and 506 kyr BP (northern Hemisphere summer at perihelion). Simulated temperature, precipitation and other relevant climatic parameters will be compared to those of MIS-5e and present-day (preindustrial) for the all Earth and with a focus on East Asia. Relationship between causes and effects will be discussed.
