  text: This study contributes to the understanding of the relationship between air
    temperature and convection by analyzing the characteristics of rainfall at the
    storm and convective rain cell scales. High spatial–temporal resolution (1 km,
    5 min) estimates from a uniquely long weather radar record (24 years) were coupled
    with near-surface air temperature over Mediterranean and semiarid regions in the
    eastern Mediterranean. In the examined temperature range (5°–25°C), the peak intensity
    of individual convective rain cells was found to increase with temperature, but
    at a lower rate than the 7%°C−1 scaling expected from the Clausius–Clapeyron relation,
    while the area of the individual convective rain cells slightly decreases or,
    at most, remains unchanged. At the storm scale, the areal convective rainfall
    was found to increase with warmer temperatures, whereas the areal nonconvective
    rainfall and the stormwide area decrease. This suggests an enhanced moisture convergence
    from the stormwide extent toward the convective rain cells. Results indicate a
    reduction in the total rainfall amounts and an increased heterogeneity of the
    spatial structure of the storm rainfall for temperatures increasing up to 25°C.
    Thermodynamic conditions, analyzed using convective available potential energy,
    were determined to be similar between Mediterranean and semiarid regions. Limitations
    in the atmospheric moisture availability when shifting from Mediterranean to semiarid
    climates were detected and explain the suppression of the intensity of the convective
    rain cells when moving toward drier regions. The relationships obtained in this
    study are relevant for nearby regions characterized by Mediterranean and semiarid
    climates.
