They vary from direct climatic forcing (like peak precipitation) to indirect (like permafrost) and partial forcing (like vegetation).

Date bunch fading disorder (DBFD) has been one of the major issues facing date palm growers in recent decades. This order has caused high and non-compensable losses to date palm product. Despite numerous studies, predominantly focusing on the causes and mitigation methods of this disorder, no precise influencing factors have been established and practices which can completely control it are not...
The relationship between plant species and climatic factors has always been an important subject in plant ecology and the use of multivariate statistical methods might be effective in detecting the relationship between climatic factors and the distribution of plant species. In the present study, climatic characteristics of Astragalus gossypinus Fisher producing tragacanth stretched in a relativ...
Background and aim: Malaria as a mosquito-borne disease is largely dependent on climatic conditions. Temperature, rainfall and relative humidity are considered as climatic factors affecting the geographical distribution of this disease. These climatic factors have definite roles not only in the growth and proliferation of the mosquito Anopheles but also in the parasite Plasmodium activity. The...
