| meteorological parameter (Variables, such as pressure, temperature, wind strength, humidity, etc. from which conclusions as to the forthcoming weather are drawn) | متغير جوي | |
| meteorological phenomenon (Phenomena which occur in the troposphere and stratosphere, such as precipitations, wind, temperature, etc.) | ظاهرة جوية | |
| meteorological research (Study of meteorological elements such as wind speed and direction, air temperature and humidity, atmospheric pressure, precipitation, evaporation, solar radiation, visibility and cloud cover in order to collect data for weather forecast or for specific research purposes) | بحوث أرصاد جوية | |
| meteorology (The science concerned with the atmosphere and its phenomena) | علم الأرصاد الجوية | |
| methane (A colourless, odourless, and tasteless gas, lighter than air and reacting violently with chlorine and bromine in sunlight, a chief component of natural gas; used as a source of methanol, acetylene, and carbon monoxide. Also known as methyl hydride, CH4) | الميثين | |
| methanization (The process of deriving methane from any source, including livestock manure, landfills, coal mines, etc.) | المَيثَنة | |
| method (A way of proceeding or doing something, especially a systematic or regular one) | أسلوب - منهج | |
| methodology (The system of methods and principles used in a particular discipline) | المنهج | |
| metrology (The science of measurement) | علم القياس | |
| metropolis (A term applied loosely to any large city, but specifically to that city in a country which is the seat of government, of ecclesiastical authority, or of commercial activity) | المتروبول - مدينة كبرى | |
| micro-organism (A microscopic organism, including bacteria, protozoans, yeast, viruses, and algae) | كائنات عضوية مجهرية | |
| microbial resource (Any available source of supply derived from microbes, which would be used for beneficial purposes, such as for the production of food substances and drugs) | مصدر ميكروبي | |
| microbiological analysis (Analysis for the identification of viruses, bacteria, fungi and parasites) | تحليل ميكروبيولوجي | |
| microbiology (The science and study of microorganisms, including protozoans, algae, fungi, bacteria, viruses, and rickettsiae) | علم الميكروبيولوجي | |
| microclimate (The local, rather uniform climate of a specific place or habitat, compared with the climate of the entire area of which it is a part) | المناخ الخاص - المناخ المحلي | |
| microclimate effect | أثر المناخ الخاص | |
| microclimatology (The study of a microclimate, including the study of profiles of temperature, moisture and wind in the lowest stratum of air, the effects of the vegetation and of shelterbelts, and the modifying effects of towns and buildings) | علم المناخ الخاص | |
| microcomputer (A microprocessor combined with input/output interface devices, some type of external memory, and the other elements required to form a working computer system; it is smaller, lower in cost, and usually slower than a minicomputer) | المايكرو كمبيوتر | |
| microecosystem (A small-scale, simplified, experimental ecosystem, laboratory- or field- based, which may be: 1. derived directly from nature (e.g. when samples of pond water are maintained subsequently by the input of artificial light and gas-exchange); or 2. built up from axenic cultures (a culture of an organism that consists of one type of organism only, i.e. that is free from any contaminating organism) until the required conditions of organisms and environment are achieved. Also known as microcosm) | النظام الإيكولوجي الخاص | |
| microelectronics (The technology of constructing circuits and devices in extremely small packages by various techniques. Also known as microminiaturization; microsystem electronics) | الإلكترونيات متناهية الصغر - الميكرو إلكترونيات |
